Periclimenes Yucatanicus
The spotted cleaner shrimp (''Periclimenes yucatanicus''), is a kind of cleaner shrimp common to the Caribbean Sea. These shrimp live among the tentacles of several species of sea anemones. They sway their body and wave their antennae in order to attract fish from which they eat dead tissue, algae and parasites. Description The spotted cleaner shrimp grows to a length of about . It has a transparent body patterned with brown and white saddle shaped markings. The chelae and legs are boldly striped in red, purple and white. There are two pairs of long white antennae banded in black. Distribution The spotted cleaner shrimp is found at depths down to about in the Caribbean Sea, southern Florida, the Bahamas and as far south as Colombia. Life cycle Breeding takes place in the summer and females have been seen brooding eggs under their abdomens in the months of July and August. After hatching, the larvae pass through several planktonic larval stages before settling on the seabed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleaner Shrimp
Cleaner shrimp is a common name for a number of swimming decapod crustaceans, that clean other organisms of parasites. They belong to any of three families, Hippolytidae (including the Pacific cleaner shrimp, ''Lysmata amboinensis''), Palaemonidae (including the spotted '' Periclimenes magnificus''), and Stenopodidae (including the banded coral shrimp, ''Stenopus hispidus'') . The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus ''Lysmata''. Cleaner shrimp are so called because they exhibit a cleaning symbiosis with client fish where the shrimp clean parasites from the fish. The fish benefit by having parasites removed from them, and the shrimp gain the nutritional value of the parasites. The shrimp also eat the mucus and parasites around the wounds of injured fish, which reduces infections and helps heali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condylactis Gigantea
''Condylactis gigantea'' is a tropical species of ball anemone that is found in shallow reefs and other shallow inshore areas in the Caribbean Sea – more specifically the West Indies – and the western Atlantic Ocean including southern Florida through the Florida Keys. It is also commonly known as: giant Caribbean sea anemone, giant golden anemone, condylactis anemone, Haitian anemone, pink-tipped anemone, purple-tipped anemone, and Florida condy. This species can easily be seen growing in lagoons or in inner reefs as either individuals or loose groups, but never as colonies. They are often used as a model organism along with others in their genus for facultative symbiosis with monocellular algae. Habitat The giant Caribbean sea anemone is usually found in the crevices of rock walls, attached to a rock, shell, or almost any other hard object in shallow water that experiences full–strength seawater most of the time, which may explain why the species is so common in Bermu ...

Cassiopea
''Cassiopea'' (upside-down jellyfish) is a genus of true jellyfish and the only members of the family Cassiopeidae. They are found in warmer coastal regions around the world, including shallow mangrove swamps, mudflats, canals, and turtle grass flats in Florida, and the Caribbean and Micronesia. The medusa usually lives upside-down on the bottom, which has earned them the common name. These jellyfish partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lie upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown. Species According to the ''World Register of Marine Species'', this genus includes 8 species: * ''Cassiopea andromeda'' (Forsskål, 1775) * '' Cassiopea depressa'' Haeckel, 1880 * '' Cassiopea frondosa'' (Pallas, 1774) * ''Cassiopea maremetens'' Gershwin, Zeidler & Davie, 2010 * '' Cassiopea medusa'' ...

Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Bartholomea Annulata
''Bartholomea annulata'' is a species of sea anemone in the family Aiptasiidae, commonly known as the ringed anemone or corkscrew anemone. It is one of the most common anemones found on reefs in the Caribbean Sea. Description The ringed anemone can reach a diameter of when fully extended. The column is short and wide and the oral disc with its central mouth can be across. There are about two hundred long, translucent tentacles ringed with whorls and spirals formed by groups of cnidocytes. The general colour is grey or brown with the cnidocyte area cream coloured. The anemone contains symbiotic zooxanthellae, single-celled algae that live within its tissues. During the day these use energy from the sun to manufacture carbohydrates by photosynthesis. The sea anemone benefits from this and the algae have a safe lodging free from the likelihood of predation. Distribution and habitat The ringed anemone is a common species in the Caribbean and Gulf of Mexico. Its range extends from ...

Lebrunia Danae
''Lebrunia neglecta'' is a species of sea anemone in the family Aliciidae. It is found in the Caribbean Sea and Gulf of Mexico. Description ''Lebrunia neglecta'' is an unusual sea anemone in that its tentacles are almost hidden by the ring of six much branching large frond-like pseudotentacles that grow up from the rim of the oral disc. These are some shade of pale or darker brown and have densely branched tips. Below these, on the side of the frond are small, whitish spherical vesicles containing nematocysts that are powerful enough to sting a human. After contact with a prey item, the pseudotentacles retract and the tentacles, which are also armed with nematocysts, grasp the prey and draw it into the mouth. The column of the anemone is usually invisible, being anchored in a crevice. This species can grow to a diameter of . It is very similar in appearance to the closely related '' Lebrunia coralligens'', but the pseudotentacles of that species are much less branched, and often ...

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Caribbean Sea
The Caribbean Sea ( es, Mar Caribe; french: Mer des Caraïbes; ht, Lanmè Karayib; jam, Kiaribiyan Sii; nl, Caraïbische Zee; pap, Laman Karibe) is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest. The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about . The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at below sea level.
