Heterosquilla tricarinata, copyright Svamp.

Belongs within: Eumalacostraca.
Contains: Squillidae, Gonodactyloidea, Lysiosquillidae.

The Hoplocarida, including the mantis shrimps and their fossil relatives, are a group of malacostracan crustaceans bearing a small carapace and at least four free thoracic segments, together with a large abdomen ending in a tail fan. They differ from other living crustaceans in being active, rapacious hunters (Schram 1979).
