Callianassa tyrrhena, from here.

Belongs within: Reptantia.

The Thalassinida, mud shrimps, are a group of thin-shelled decapods that construct complex burrows in muddy substrates. The first pereiopods of Thalassinida are chelate or subchelate; the second pereiopods are simple or subchelate in Laomediidae, Upogebiidae and Thalassinidae, but chelate in members of the remaining families.

Synapomorphies (from Dixon et al. 2003): Eyes of apposition type. Pereiopod 1 with curved articulation between ischium and merus; row of setae present on pereiopod 2. Seventh thoracic sternite enlarged and lobate.
