Ecology Summary - Diademichthys lineatus

Língua:

Ref. principal	Sakashita, H., 1992
Notas	The association od D. lineatus with Diadema is not obligatory, so Diadema may not be essential for the adult fish, but juveniles use the host for shelter and food and it may be difficult for them to survive without Diadema. The fish does not appear to be beneficial or harmful to its host. It eats only a small quantity of tube feet and the damage inflicted on Diadema is not severe. Females have a narrower and longer snout which is suitable for taking small parts from animals. Consequently, they eat more shrimp eggs and gills of bivalves Males eat more tube feet of sea urchins (Ref. 33619).
