Pederson's Shrimp
''Ancylomenes pedersoni'', sometimes known as Pederson's shrimp and Pederson's cleaner shrimp, is a species of cleaner shrimp. It is part of the genus ''Ancylomenes'' and was described in 1958 by Fenner A. Chace Jr. as ''Periclimenes pedersoni''. ''Ancylomenes pedersoni'' is found in the Caribbean Sea, often associated with a sea anemone, at depths of . They are often found on the reefs off Bermuda. Description Pederson's shrimp is a small transparent shrimp with bluish and violet markings on the body and long white antennae and within its range is unlikely to be confused with other species. Ecology Pederson's shrimp lives in association with a sea anemone, either ''Bartholomea annulata'' or '' Condylactis gigantea'', living among the tentacles with impunity. Before it can do this it needs to acclimatise itself to the anemone by progressively pressing its body and appendages against the tentacles for increasing periods of time. After this it is able to move between the tentacle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans Described In 1958
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Palaemonoidea
Palaemonoidea is a large superfamily of shrimp, containing nearly 1,000 species. The position of the family Typhlocarididae is unclear, although the monophyly of a group containing the remaining seven families is well supported. *Anchistioididae Borradaile, 1915 * Desmocarididae Borradaile, 1915 *Euryrhynchidae Holthuis, 1950 *Gnathophyllidae Dana, 1852 *Hymenoceridae Ortmann, 1890 *Kakaducarididae Bruce, 1993 *Palaemonidae Rafinesque, 1815 *Typhlocarididae Annandale & Kemp, 1913 Image:Gnathophyllum americanum Réunion.JPG, ''Gnathophyllum americanum'', a Palaemonidae Image:Harlequin Shrimp 1.jpg, ''Hymenocera picta'', the only Hymenoceridae Image:Emperor Shrimp - Periclimenes imperator.jpg, ''Periclimenes imperator'', a Palaemonidae Image:Typhlocaris ayyaloni cropped.jpg, ''Typhlocaris ayyaloni'', a Typhlocarididae ''Typhlocaris'' is a genus of blind cave-dwelling shrimp, placed in its own family, Typhlocarididae.

Neon Goby
''Elacatinus'' is a genus of small marine gobies, often known collectively as the neon gobies. Although only one species, ''E. oceanops'', is technically the "neon goby," because of their similar appearance, other members of the genus are generally labeled neon gobies, as well. Except for a single East Pacific species, all reside in warmer parts of the West Atlantic, including the Caribbean and Gulf of Mexico. They are known for engaging in symbiosis with other marine creatures by providing them cleaning service that consists of getting rid of ectoparasites on their bodies. In return, ''Elacatinus'' species obtain their primary source of food, ectoparasites. Species Currently, 24 recognized species are placed in this genus: * ''Elacatinus atronasus'' J. E. Böhlke & C. R. Robins, 1968 * ''Elacatinus cayman'' Victor, 2014 (Cayman cleaner goby) * ''Elacatinus centralis'' Victor, 2014 (Cayman sponge goby) * ''Elacatinus chancei'' Beebe & Hollister, 1933 (shortstripe goby) * ''El ...

Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Cleaning Station
A cleaning station is a location where aquatic life congregate to be cleaned by smaller creatures. Such stations exist in both freshwater and marine environments, and are used by animals including fish, sea turtles and hippos, referred to as clients. The cleaning process includes the removal of parasites from the animal's body (both externally and internally), and is performed by various smaller animals including cleaner shrimp and numerous species of cleaner fish, especially wrasses and gobies (''Elacatinus spp''.), collectively referred to as cleaners. When the animal approaches a cleaning station, it will open its mouth wide or position its body in such a way as to signal that it needs to be cleaned. The cleaner fish will then remove and eat the parasites from the skin, even swimming into the mouth and gills of any fish being cleaned. This is a form of cleaning symbiosis. How predator clients recognize cleaners is still uncertain. It has been hypothesized that color, size, a ... [...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 ...

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 ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...
