AB -  and A major chemosensory structure of deca- pod crustaceans is the lateral branch of the bi- ramous first antennae (antennules). This ap- pendage contains many aesthetasc sensilla which have a thin, porous cuticle and con- tain the chemosensory endings of large num- bers of sensory cells (Ghiradella et al., 1968; Tierney et al., 1986; Laverack, 1988). In con- trast, the chemosensory sensilla found on other regions of the body have a much thicker cuticle and are innervated by only a handful of chemosensory cells (Laverack, 1988). The importance of antennules is illustrated by findings which show that crayfish can use chemosensory information to determine the sex of a conspecific only if their antennules are intact (Ameyaw-Akumfi and Hazlett, 1975; Dunham and Oh, 1992). Other chemo- sensory sites cannot perform this function. If antennules are indeed important for sex recognition, one would expect the loss of an- tennules to perturb mating behavior. Work on a number of crustaceans has consistently shown that antennule ablation or restriction interferes with normal courtship or mating (Christofferson, 1972; Gleeson, 1980; Cowan, 1991; Bamber and Naylor, 1996), while ab- sence of vision does not (Gleeson, 1980; Sny- der et al., 1992). We performed antennule
