Abstract

REPRODUCTION IN THE BURROWING CRAB, CORYSTES CASSIVELAUNUS (PENNANT, 1777) (DECAPODA, BRACHYURA) BY R. G. HARTNOLL Marine Biological Station, Port Erin, Isle of Man, Great Britain INTRODUCTION Corystes cassivelaunits is the only British representative of the family Corysti- dae. It occurs on sublittoral sand, in which it spends much of its time completely buried. There are certain features of special interest in this crab. One is the exceptional length of the second antennae, which are used as an aid to respiration while the crab is buried. Each antenna bears two rows of long setae, and when buried the crab holds the two antennae parallel to each other so that their setae intermesh. The setae exclude sand from the passage between the antennae, and the inspiratory current is drawn down this passage from the surface. When a crab is completely buried the tips of the antennae are at the bottom of a small depression in the sand, or may even be hidden beneath the sand. A second feature of Cor)lstes is the very marked sexual dimorphism of the chelae, which are relatively much longer in large ma.les than in other specimens.
