Synchronized courtship in fiddler crabs

Article Abstract:

Quantitative evidence is provided for synchronous production of a conventional visual courtship signal, the movement of a body part in the fiddler crab Uca annulipes. This was based on video recordings of females and clustered waving males, with timings of waves made by each male documented. It is concluded that visual signal perception and processing mechanisms must have properties previously believed to restrict synchronized courtship signalling to acoustic and bioluminescent routes.

Ancient homes for hard-up hermit crabs

Article Abstract:

It has been established that the tropical, semi-terrestrial hermit crab Coenobita rugosus will use fossil shells when there is no other appropriate casing available. The shells drop out of coastal limestone as it is eroded by the sea in southwestern Madagascar.
