Lysmata Wurdemanni
''Lysmata wurdemanni'', commonly known as the peppermint shrimp, is a species of shrimp. Description It reaches in length, and is named for the bright red stripes on its otherwise translucent body, which are reminiscent of peppermint candies such as a candy cane. Its eggs, by contrast, are bright green. Distribution ''Lysmata wurdemanni'' was originally described from specimens collected at Key West, Florida and Charleston, South Carolina. Its range extends along the Atlantic seaboard of the United States from Long Island to Florida, and along the Gulf of Mexico from Florida to Port Aransas, Texas. It may also occur in the northern Caribbean Sea, but this has not been confirmed. Reproduction ''Lysmata wurdemanni'' is a protandric simultaneous hermaphrodite. This means that it begins as a male but may later become a hermaphrodite. It has four moults as a male before changing sexes to become a euhermaphrodite. However, under certain conditions some males never change to hermap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caridea
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp. Biology Carideans are found in every kind of aquatic habitat, with the majority of species being marine. Around a quarter of the described species are found in fresh water, however, including almost all the members of the species-rich family Atyidae and the Palaemonidae subfamily Palaemoninae. They include several commercially important species, such as ''Macrobrachium rosenbergii'', and are found on every continent except Antarctica. The marine species are found at depths to , and from the tropics to the polar regions. In addition to the great variety in ...

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 ...

Lysmata Boggessii
''Lysmata'' is a genus of shrimp in the infraorder Caridea, the caridean shrimp. The genus belongs to the family Lysmatidae. ''Lysmata'' are popular ornamental shrimp in the marine aquarium trade for their bright color patterns, interesting behaviors, and ability to control certain aquarium pests such as sea anemones of the genus ''Aiptasia''. They are known to command high prices on the pet market. The genus is informally divided into two main categories. Some species are cleaner shrimp which "clean" parasites and other material from fish, live in pairs, and are brightly colored, often in contrasting reds and yellows with white antennae. Other species are the "peppermint shrimp", which have semi-translucent, red-banded bodies, and live in large groups. Some peppermint shrimp perform cleaning behaviors, but less actively than do the cleaner shrimp. The genus has been studied with interest due to its unusual sexual system, protandric simultaneous hermaphroditism. While some oth ...

Zoea
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more-so than where the larvae are planktonic, and thereby easily caught. Many crustacean larvae were not immediately recognised as larvae when they were discovered, and were described as new genera and species. The names of these genera have become generalised to cover specific larval stages across wide groups of crustaceans, such as ''zoea'' and ''nauplius''. Other terms described forms which are only found in particular groups, such as the ''glaucothoe'' of hermit crabs, or the ''phyllosoma'' of slippe ...

Lysmata Debelius
''Lysmata debelius'' is a species of cleaner shrimp indigenous to the Indo-Pacific. It is popular in the aquarium trade, where it is known as the fire shrimp, blood shrimp or scarlet cleaner shrimp. Taxonomy ''Lysmata debelius'' was first described by A. J. Bruce in 1983, based on type material from Polillo Island in the Philippines. The specific epithet commemorates Helmut Debelius, who had collected the specimens and sent them to a zoologist for identification. A divergent population from Ari Atoll in the Maldives was later described as a separate species, '' L. splendida'', by Rudolf Burukovsky. Description ''Lysmata debelius'' grows up to long, with males and functional hermaphrodites appearing similar. It has a red body, with conspicuous white antennae and white tips to the third to fifth pereiopods. There are white dots on the cephalothorax and legs; white dots on the abdomen distinguish ''L. splendida'' from ''L. debelius''. Ecology ''Lysmata debelius'' is one of a gro ...

Copulation (zoology)
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many animals that live in water use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates (such as all reptiles, some fish, and most bird Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweig ...s) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while mammals copulate vaginally, and many primitive (biology), basal vertebrates reproduce sexually with external fertilization.

Aiptasia
''Aiptasia'' is a genus of a symbiotic cnidarian belonging to the class Anthozoa ( sea anemones, corals). ''Aiptasia'' is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the genus ''Symbiodinium'' living inside nutritive cells. The symbionts provide food mainly in the form of lipids and sugars produced from photosynthesis to the host while the hosts provides inorganic nutrients and a constant and protective environment to the algae. Species of ''Aiptasia'' are relatively weedy anemones able to withstand a relatively wide range of salinities and other water quality conditions. In the case of ''A. pallida'' and ''A. pulchella'', their hardiness coupled with their ability to reproduce very quickly and out-compete other species in culture gives these anemones the ...

Marine Aquarium
A marine aquarium is an aquarium that keeps ocean, marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquarium, reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
