Stinger 

 Habitat Many even eat other jellies. Present in the mid and northern seas of Italy, it is increasingly more frequent along our coasts. The colony is 3-7 cm long, and the blue polyps are attached to a round chitinous float. The umbrella is about 10 cm in diameter, and is armed with 8 long tentacles that, when extended, can reach also 10 m length. Relatively small, transparent, with cubic umbrella measuring from 4 to 5 cm, it is armed with 4 long tentacles. These jellyfish sit on their dome with their tentacles extended upward toward the sunlight. Habitat 
 A fine fringe of tentacles runs around the lower edge of the dome. These large jellyfish, often present in great quantities, can become microcosms that are used by other organisms: they are often a shelter for juvenile fish and small crabs can find a refuge among their oral arms. Just as for Rhizostoma, it is often associated to young fish that use it as a shelter. Their tentacles, on the other hand, can reach up to 200 feet. It reappeared also in 2010 and 2011. ... Jellyfish tentacles can trail the body of the jellyfish up to 165 feet in length, (Portuguese man-of-war) but most common 10 feet horizontally or vertically in the water and are not easily seen. It can be present in enormous swarms, several km long. Since the jellyfish can eat also the eggs and larvae of fish, the impact on fish stocks, and then on fisheries, can be equally devastating. It is a beautiful animal and, in some countries, it is used as food. Habitat 
 The genus Rhopilema is typical of the Indo-Pacific ocean and has no Atlantic or Mediterranean representatives. How to identify it 
 Never very abundant along our shores, even though it can be in large swarms locally, especially in spring. Hawaii. Under the umbrella, the manubrium resembles a bouquet of flowers, with blue-purple buttons, inserted into stout arms. The diamater can be 30 cm maximum, the jellyfish usually rests on the sea bottom, with the umbrella towards the bottom, whereas mouth and tentacles are upwards. It is the largest Mediterranean jellyfish (after the rare Drymonema): the umbrella can reach a diameter of 60 cm and it weight 10 kg. Some species live in the cold Arctic water and others live in the warm tropical waters. We have had a few reports around The Bahamas of box jellyfish known as Sea Wasps (now Alatina sp, but formerly Carybdea alata) showing up. Rays have special organs generating electric current. The upper part of the umbrella is decorated by 15 V-shaped bands that start from the centre of the umbrella and reach the margin, where there are 24 tentacles, in groups of 3. Inevitably the swarms reach the coast and strand on it, but this happens usually at the end of the life cycles, when the medusae already detached from the colonies. In some cases, the encounter with Physalia can be deadly. Less common than Velella in the Mediterranean Sea, it floats on the surface of the sea, just as Physalia and Velella. Local common names are used, if known. Most people think that all gelatinous,swimming marine animal encountered at the sea are "jellyfish" and  moreover that they all sting. Withish or blusish, and covered with yellow spots, hence the name: the spotted jellyfish. Habitat
 Stinger 

 In the eastern Mediterranean it causes great harm to tourism, fisheries, and industry. It is similar to Rhyzostoma pulmo but it does not have the typical bluish-purple umbrellar margin typical of this species. It lives in the Atlantic, and it can reach high latitudes, for instance Norwegian fjords, where it can be present in thick swarms. Mild Stinger

 Not a Stinger 
 The upside-down jellyfish is often found in the warm mangrove islands in Florida and the Bahamas. Stinger Physalia has been recorded from the Mediterranean Sea since ancient times, but is never frequent. The order Coronatae includes about 30 species of mostly deep-sea jellyfish, often maroon in colour. It originates from Australia. Habitat 
 The umbrella can reach 30 cm in diameter, the manubrium (the organ hanging from the centre of the umbrella, with the mouth at its end) has four oral arms that can be even 1 m long. Species Name Scientific Name Group Range; 1. Are you inspired by endangered animals? This behavior let them keep their tentacles spread over a larger area and help them capture food at ease. It is attracted by light and gets near the coast during the night. lives in all oceans of the northern hemisphere, where it can be very abundant. 11/52 SLIDES © Georgette Douwma/Getty Images. How to identify it A bad stinger, it can be confused with the almost harmless Rhizostoma from which it can be distinguished due to the characteristic blue rim of Rhizostoma. Flabellina nudibranch. Drymonema is a very rare species, very similar to the largest jellyfish of the world, the northern Cyanea capillata with even 2 m of umbrellar diameter. Just as Pelagia, it is typical of the Mediterranean and is one of the most stinging species of our seas. In places like Cuba, Colombia and the Bahamas, governments have encouraged their populations to start eating the fish to keep down numbers. Summer in the Bahamas is Jellyfish season and I think they are fascinating marine creatures. Carybdea marsupialis is a cubozoan, as the deadly jellyfish that inhabit Australian coasts. Mr. Ringers tosses the medusas caught in his nets back into the ocean. Discovered in 2010 along the coasts of Israel by the marine scientist Bella Galil. There are various species of sea urchins with widespread distribution. Jellyfish species vary greatly in size, ranging from the eraser tip of a pencil to about eight feet in diameter. Plenty of other shark species can also be found here, and the Bahamas enjoys a huge cage diving industry, fueled by adventurous visitors who want to get as close as they can to the sharks that live here. Recently, it re-appeared in Croatian coasts and it can easily reach the Italian waters. American Mahogany As for the dolpins, you really need to book in advance for this one, but maybe they will have a cancellation and you can get in (there isn't any bargining for this) try their website and maybe a discount of 10% is available for booking on line. A strong stinger, it might be dangerous due to its large size. Its stinging properties resemble those of Pelagia, but it is a less severe stinger. Salp chains can reach 6 m. The massive presences of this species are sudden and can last just a few days. There are thousands of beaches in the Bahamas, and it's important to be on the lookout for jellyfish no matter where you go. Check out our It is common along Portuguese coast and, in general, throughout the Atlantic Ocean, but it was never recorded from the Mediterranean Sea, until Maria Ghelia photographed it in 2010, in the waters of the Pantelleria Island. Acropora Coral: Acropora cervicornis: Corals, Jellyfish, and Sea Anemones: Central America, Gulf of Mexico, North America (United States Territory) 3. It can be present in swarms, but it usually less abundant and frequent than Velella. The current global warming might pave its way towards the expansion of this species in the Western Mediterranean. Mild Stinger 
 Because jellyfish potentially both compete with and prey on fish, changes in their numbers may alter ecosystems and affect commercially important fish species. Mild Stinger How to identify it
 Jellyfish Habitat Facts and Information . The effects can persist even for a relatively long time. In the early Eighties, Pelagia was abundant throughout the Mediterranean Sea, then it disappeared to reappear at more or less decadal intervals but, since the very hot 2003, its presence is rather constant in the western Mediterranean. Two fairy crabs (Lauriea siagiani). Not big (max 10 cm) and harmless because its cnidocysts are not dangerous for humans. It never reached the Italian seas, possibly because the temperatures are not high enough for this tropical species. Luckily, its venom is not deadly: its stings are painful, but the effects last just a short while. Category Travel & Events; Show more Show less. The tentacles are short and are armed with cnidocysts that are not very painful, but they can cause mild rashes if touched with insistence. How to identify it Salps have neither cnidocysts nor colloblasts and, thus, are harmless to humans, but their massive presence can impoverish the sea by removing primary producers (the phytoplankton). The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. A school of goggle-eye … The most obvious are the Moon Jellies, smooth discs of faintly purple jelly, with four lilac rings grouped around the centre (the sex organs). There are up to 200 different species of Jellyfish such as Lion’s Mane, Portuguese Man-of-War, Cannonball Jelly, and Sea Nettle. It comes from the Red Sea, where it probably passed unobserved, and entered the Mediterranean from the Suez Canal. It is harmless for humans but extremely dangerous for the eggs and the larvae of fish, having the possibility of changing the functioning of ecosystems, as it did in the Black Sea, where it is a very unwelcome alien. Habitat 
 List of all endangered species (animals & plants). The colonies produce small jellyfish that probably then give rise to a series of stages that resemble those of Velella. The discovery of this protein allowed the development of new techinques for diagnosing pathologies and research in molecular biology. With over 2,000 species out there they have been able to find plenty of locations where they can thrive. Palau has many excellent dive operators, like Splash Dive Center, Palau Diving Center, Sam’s Tours Dive Shop, and Fish ‘N Fins. Probably Drymonema spends long periods on the bottom of the sea, as little polyps attached to rocks. They are distinguished by a saucer-like shape on the top and tentacles hanging below as thick as a lion’s mane. How to identify it
 Also known as the By-the-wind sailor, it is not a jellyfish but a floating colony of polyps. With their help, I plan to explore some of Palau’s 1,450 species of fish and 500 species of coral. How to identify it
 Hence it is both a predator and a competitor of fish and it can cause the impoverishment of the seas. Each nematocyst contains a stinging thread that is coiled. Moon jellyfish (Aurelia aurita) are found in nearly all the world’s oceans, primarily in inshore regions like harbors and estuaries. The umbrella can measure 30 cm in diameter, it is very rigid and roundish in its centre, where it has a reddish or yellow color. Each tentacle is equipped with thousands of cells known as cnidoblasts which contain nematocysts inside. More to come soon. The manubrium is large and it looks like a white cauliflower. Habitat Stinger 

 Included among these are members of the genera Aurelia and Chrysaora and the big red jellyfish, Tiburonia granrojo (subfamily Tiburoniinae), one of only three species of jellyfish that lack tentacles. This height can be compared to that of two blue whales. It has this posture because there are unicellular algae in its tissues, similar to the symbiotic algae of tropical corals, and they are also symbiotic with the jellyfish that, to make them function properly, has to expose them to light. How to identify it
 It is not a bad stinger, but it is better not to touch it.

Pin. Stung people rarely see the animal, but they feel a very painful sting. Some years ago it formed extensive swarms along the Florida coasts, causing a sudden crash in fish populations. Physalia has a large bladder full of gas, the pneumatophore, the float of a colony of polyps with a mouth, that digest the prey, and polyps armed with stinging cells containing a powerful venom, extremely efficent also with humans. Lion’s mane jellyfish is the largest known species of jellyfish. games and coloring pages! Habitat 
 How to identify it
 They sometimes migrate in small groups in search of food. Habitat 
 This discovery led to application in diagnostics, allowing to mark specific cell lines. These jellyfish range considerably in size from 3-4” in diameter to an incredible 3’. Mild Stinger After a period of rest on the bottom, it pulsates vigorously towards the surface, and then falls towards the bottom again, with its tentacles extended through the water. It is harmless to humans, but it is better not to touch it anyway. It is not very dangerous, but it is better not to touch it because it produces mucus with dispersed stinging cells, and entering in contact with this mucus causes irritations. It entered the Mediterranean Sea through the Suez Canal, and is expanding through the Turkis coasts. During the sinking phase, the jellyfish catches the plankton that makes up its food. Thalia democratica derives its name from its ability of forming long chains of barrell-shaped zooids, with an evident orange spot that is evident through the transparent body. What also lives there that may consume the Jellyfish can vary. Aurelia lives in all oceans of the northern hemisphere, where it can be very abundant. These creatures prefer warm waters, and typically live upside-down on the sea-bottom, which no doubt makes catching prey very simple. A barrel jellyfish (Rhizostoma pulmo) is seen in the Mediterranean Sea. How to identify it
 Philippines. Most jellyfish stings in the western Mediterranean are from this species. The manubrium has four long oral arms. In 2010 it was recorded at Malta, and so it reached the Italian waters. Pin. The adult jelly can also shrink when food is not available to conserve energy and resources, growing back to its normal size when food becomes available again. It is probably harmless also for most fishes. How to identify it
 It is a delicacy for several oriental people. It is a ctenophore and not a cnidarian, so it is gelatinous but it is not a stinger, simply because it does not have stinging cells. The polyps can live (just as little corals) for decades and then, all of a sudden, they can produce jellyfish. They never form extensive swarms, but they can be locally abundant. Its stings are not severe, but they are painful enough to spoil your day. We didn’t spot any of them, and we later learned that they evolved to shrink to a third of their size (the size of our fingertip). Physalia, also known as Portuguese Man of War, does not live suspended in the water, as most gelatinous plankters, but it floats on the surface of the sea, the tentacles hanging downwards. Habitat 
 Some species of rays are dangerous for people as their current is strong enough to stun humans, while the Dasyatis species can even cause painful wounds. The fourth species was the box jellyfish (carybdeidae), which is known to be one of the most venomous jellyfish in the world. It is placed in the same family of Rhizostoma, and can reach the size of this large jelly (even more than 50 cm of bell diameter) sharing also its general structure. The Caribbean Sea Wasp has 4 long tentacles, one on each side of its cube shaped bell. It is easily distinguished from other jellyfish because it has many radial canals that link the centre and the margin of the flat bell. The colonies produce small jellyfish that sink, reproduce sexually giving rise to the conaria stage that then transforms in a series of stages that, from the deep sea, reach the surface and become the new colonies. These curious creatures of the sea, appear as jelly-like, shapeless, blobs on land, but in water, they are extremely dangerous, graceful and elusive. Like most other jellyfish species, the moon jellyfish move around horizontally, swimming by pulsation of the bell-shaped upper part that always stays close to the water surface. Jellyfish have been in existence for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal group. Found in the freezing waters of the Arctic ocean and the Northern Pacific Ocean, they are known to … Seeing it rising from the bottom gives the impression of being attacked, but it is just an impression. A spotted cleaner shrimp (Periclimenes yucatanicus) in a pink-tipped anemone. Photo by PVA Snorkeling in Palau. It does not have a single mouth but many small mouths instead. In the summer, it can be present in persistent swarms that can spoil the tourist season even for months. Hi Mare, I don't know about the jellyfish, as we went in June and didn't have any problem at all. Many radial canals link the centre and the margin of the umbrella. Habitat 
 Cotylorhiza can have symbiotic microalgae that live in its tissues, just as those of tropical corals. How is it possible that an animal of this size can remain undetected for decades? It buds laterally from polyps that live on the sea bottom. Stinger 

 Just as Rhizostoma, it does not inflict painful stings and is not a menace for swimmers, unless the contact is very intense. How to identify it
 For many years that description was the only sign of existence of this species but in 1940 another researcher (Stiasny) found it again on the east coast of the Adriatic Sea. Hence the name: mauve stinger. All SPECIES BY COMMON NAME: Grouped by genus. Typically, there will be blooms of Sea Wasps (as a result of spawning) around 10 days after a full moon. In 2009 it was more frequent in the southern part of Italy, showing a preference for warmer waters, but this was not confirmed in 2010 and 2011, since this species was very frequent throughout the whole Italian coast, especially in the second half of the summer. It is abundant along our coasts. The mouth and the manubrium are inserted in a gelatinous bulg that originates from the centre of the bell and projects downwards. However, it is believed that as man continues to explore the depths of the ocean, many more species will be encountered. Mnemiopsis leidy is a ctenphore, a gelatinous organism a little more than 10 cm long, with an egg-shaped lobate body. Mild Stinger 
 From this jellyfish genus, the green fluorescent protein (GFP) was isolated a substance that produces light in many jellyfish. It is edible. The venom of Aurelia is harmless for humans and this jellyfish can be touched (in China it is a popular dish) even though, like all jellyfish it is very delicate and contacts can damage it. The external part of the manubrium is motile and pulsates vigorously. Common in the Mediterranean Sea, it floats on the surface of the sea, just as Physalia. Increases in populations of jellyfish in areas around the world have captured the attention of scientists in recent decades. When fish or any other object is tangled in the tentacles… Heckel, the great naturalist, described it in 1880: a large jellyfish along the Dalmatian coast, in the Adriatic Sea, and he called it Drymonema dalmatinum. It swims vigorously and moves quickly. Bahamas. Also known as Blue-button Jellyfish, it is not a jellyfish but a floating colony of polyps. It does not have a large size, reaching a max of 10 cm in diameter. And there aren't any reports on the species' diet, but like other jellyfish, it probably eats small fish, crustaceans and other jellyfish, Gruber said. Some tentacles, also terminating with blue buttons, are inserted on the manubrium. Here is a mini-guide to the main jellyfish species and the most recognizable gelatinous plankton species prevalent in our seas. It is a thaliacean, and so it is a herbivorous gelatinous plankter that filters the water through its mucus-laden gills, that trap phytoplankton and bacteria. Jellyfish stings can … They can also enter the cooling systems of power plants, and block it. For this reason, the species is called the upside down jellyfish. The free-swimming adult jellyfish often eat a variety of marine species from tiny shrimp to small pelagic fish. Acropora Coral: Acropora palmata: Corals, Jellyfish, and Sea Anemones: Central America, Gulf of Mexico, North America (United States Territory) 2. Mild Stinger 

 Even though Jellyfish are made up of more that 95% water and can’t swim, they are one of the greatest predators of ocean life. Habitat 
 But not all jellyfish are stinging; many are harmless to humans, but it is always best to avoid touching them. Habitat The larger a Jellyfish is the less likely it is to be bothered by some predators. The coral reefs off the coast of Nassau Paradise Island are the third longest in the world, and they’re home to an incredible array of tropical marine life! Collected pink jellyfish (Pelagia species). How to identify it
 It feeds on crustacean plankton and, probably, also of fish eggs and larvae. The american researchers Osamu Shimomura, Martin Chalfie and Roger Tsien were awarded the 2008 Nobel prize in chemistry for their discovery of GFP. This is the worst stinger of the whole Mediterranean, in terms of number of stung people. It is a hydromedusa that buds from polyps that live on the sea bottom. Humpback shrimp (Saron sp.). The Mangrove Jellyfish Cassiopea, also called the ‘upside-down jellyfish’ for reasons I needn’t dwell on, is the only member of its particular jellyfish family. This species is rare so far, and there is not much information about its effects on humans, apparently it is not a stinger. In the Eighties this species became suddenly abundant along the Israeli coasts of the Mediterranean Sea: it probably reached the Mediterranean from the Red Sea, through the Suez Canal, hence the specific name “nomadica”. The stings can be very painful and can leave scars on the skin. Head on shot of a shrimp's eyes. It is a hydromedusa, just as Aequorea forskalea, but it is a stinger even if it is smaller than Aequorea, reaching 6 cm in umbrellar diameter. Cuba now holds an annual fishing tournament for the species. In the summer of 2010 a woman was killed by Physalia in Sardinia, and many swimmers were sent to hospital by this dangerous stinger. The mouth has four long oral arms, the color of the whole animal is mauve. Habitat How to identify it Would you like to receive a notice and link when the Habitat 
 The habitat for Jellyfish is very vast as they can live in any ocean water. In 2009 a specimen was seen for the first time along the Italian coast, at Tavolara Island, in Sardinia. Spotted spiny lobster (Panulirus guttatus). Philippines. Fiji. The pneumatophore can measure 15 cm, but the extended tentacles can reach even 20 or 30 m. Mild Stinger The name of the species (stellata) describes star-like reddis spots that adorn the umbrella. Because its locomotion is rather limited, this species prefers temperate waters with regular currents that can help push it through the water column. Yet sometimes it really doesn’t matter because the predator is so large. Habitat Stinger

 The swarms can be very thick and if they invade a cage aquaculture plant, the effect can be devastating. Stinger 
 In 2009 it stund several people in the Eastern Mediterranean, in Corsica, in Ligury and in Tuscany. Then complete oblivion for this species, until when Drymonema became a pest, for some time, along the coasts of Puerto Rico. Jellyfish. It does not pass unnoticed, since it can reach 80 cm in diameter and can form extensive swarms. Very abundant in the Mediterranean Sea, expecially in bays. Also Drymonema can reach a remarkable size: it can be even 1 m in diameter and it is the largest jellyfish of the Mediterranean Sea. If you see it, a picture is needed to confirm your record. Sometimes just a few, so as to produce new polyps with sexual reproduction. The colony is 3-7 cm long, and the blue polyps are attached to a chitinous float with a “sail” that makes the animal travel by using wind energy. Functionally it is a “plant”, even if it can feed on zooplankton.
