Association between juvenile reef fish and the Caribbean reef squid Sepioteuthis sepioidea on north-eastern Brazilian coastal reefs

This article reports on four different juvenile reef fish species, Polydactylus virginicus, Haemulon aurolineatum, H. steindachneri and Carangoides bartholomaei swimming along with schools of the caribbean reef squid Sepioteuthis sepioidea. Three different behaviours were observed. This is the first record of this squid species on Brazilian reef habitats. We suggest that this behaviour is mainly related to protection for juvenile fish against potential pelagic predators.
