Abstract
This first description of behavioural interactions between benthic pyjama sharksPoroderma africanum(Chondrichthyes: Scyliorhinidae) and spawning squidsLoligo vulgaris reynaudii(Cephalopoda: Loliginidae) was made from underwater video recordings. The behaviours are described and illustrated to show that the sharks searched for squids in egg beds, then rested there partially hidden and immobile. The pyjama sharks at-tempted to ambush the squids when they approached to lay their eggs after they had apparently habituated to the predators. Although normally nocturnal, the pyjama sharks had emerged by day from caves and cracks in the rocky reef to attack the spawning squids, thereby benefiting from an occasionally available resource.
