Tanaidacea

Belongs within: Eumalacostraca.
Contains: Leptocheliidae, Nototanaididae, Anarthrurinae, Pseudotanaididae, Colletteidae.

The Tanaidacea are a group of burrowing aquatic crustaceans with the second thoracopods formed into a pair of large chelae. The cephalothorax is formed from the head and two thoracic segments with the carapace fused dorsally to both those segments (Ax 1999). Most tanaidaceans are less than 5 mm in length, but at least one species reaches close to 8 cm. Members of the Tanaidomorpha live in tubes which they construct by gluing together debris; other tanaidaceans are free-living or burrowing.
