Coenobita Abdominal Appendages

The abdominal appendages of the land hermit crab include the thoracic appendages, pleopods, uropods and telson [1].
The thoracic appendages are used for cleaning the gills, gripping the shell, gripping a mate during copulation.

The pleopods are used for brooding eggs.

At the end of the pleon is the tail fan, comprising a pair of biramous uropods and the telson, which bears the anus. Together, they are used for steering while swimming, and in the caridoid escape reaction.
