Tanaidacea
The crustacean order Tanaidacea (known as tanaids) make up a minor group within the class (biology), class Malacostraca. There are about 940 species in this order. Description Tanaids are small, shrimp-like creatures ranging from in adult size, with most species being from . Their carapace covers the first two segments of the thorax. There are three pairs of limbs on the thorax; a small pair of maxillipeds, a pair of large clawed gnathopods, and a pair of pereiopods adapted for burrowing into the mud. The remaining six thoracic segments each bear a pair of pereiopods, and each of the first five abdomen, abdominal segments normally carry pleopods. The final segment is fused with the telson and carries a pair of uropods. The gills lie on the inner surface of the carapace. The thoracic limbs wash water towards the mouth, filtering out small particles of food with the mouthparts or maxillipeds. Some species actively hunt prey, either as their only food source, or in combination with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malacostraca
Malacostraca is the second largest of the six classes of pancrustaceans behind insects, containing about 40,000 living species, divided among 16 orders. Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, spiny lobsters, crayfish, shrimp, krill, prawns, isopods, amphipods, mantis shrimp, and many other less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats. They are segmented animals, united by a common body plan comprising 20 body segments (rarely 21), and divided into a head, thorax, and abdomen. Etymology The name Malacostraca is . The word was used by Aristotle, who contrasted them with oysters, in comparison with which their shells are pliable. It was applied to this taxon by French zoologist Pierre André Latreille in 1802. He was curator of the arthropod collection at the National Museum of Natural History in Paris. This scientific name is misl ...
