Open publisher page 141 citations

Abstract

Male crayfish, Procambarus clarkii, show different behaviors toward males (aggression) and females (submission, courtship). Behavioral and neurophysiological tests with water in which the crayfish had been held demonstrated the existence of sex pheromones. The inner rami of the antennules are the site of reception, and the chemicals are probably carbohydrates.
