Bryozoan-Associated Decapod Crustaceans: Community Patterns and a Case of Cleaning Symbiosis Between a Shrimp and Crab
Twenty-three species of decapod crustaceans were collected from 185 heads of the bryozoan Schizoporella pungens. Numbers of species increased significantly with increasing head size, as did numbers of individuals. Abundances of juveniles of dominant species were proportional to bryozoan head size, but numbers of males were not. Numbers of females were related to head size for second ranked Thor manningi, but not for top ranked Pilumnus sayi nor third ranked Pelia mutica. P. sayi comprised 50.4% of the total number of individuals, while T. mallningi comprised 27.8%. T. manningi was observed cleaning P. sayi in the laboratory, and these two species demonstrated a significant positive association in field samples.
