The olfactory sense organs of crayfish are aesthetasc sensilla, arrayed along the distal half of the lateral antennular flagella on each side of the animal. The sensillar array is sparse at its proximal origin, where each annulus houses only a single aesthetasc, and it is most dense distally, with occasionally up to six aesthetascs residing on each antennular annulus. Previous studies have tacitly assumed that the aesthetascs are co-equal in their functional properties. We restricted exposure… CONTINUE READING
