Stomatopoeia - stomatopod

Japanese: 口脚類 - こうきゃくるい(英語表記)stomatopod
Stomatopoeia - stomatopod
A general term for crustaceans classified under the order Stomatopoda of the class Malacostraca. Commonly known as the mantis shrimp (→ Mantis shrimp). Its most distinctive feature is that the second thoracic leg is a prehensile like a praying mantis's claws. There are two types of mantis shrimp: the mantis shrimp type, which has a row of sharp spines on its prehensile leg (which pinches prey) and the mantis shrimp type, which has no spines but has a round bulge at the base (which strikes prey). The carapace is small and only covers the first four thoracic segments. The exposed thoracic segments 5 to 8 are called free thoracic segments and at first glance look like the abdomen. The thoracic segments 6 to 8 each have a pair of bifurcated thoracic legs. They are all marine species, found from the coast to the deep sea, with about 2,000 known species in 17 families. Many species are edible. (→ Arthropods, Malacostraca)
