 For example, in False Bay the Cape rock lobster ("Jasus lalandii") is the most important food source, followed by cephalopods and then fish.Pyjama sharks have been observed seizing and tearing off tentacles from octopus and cuttlefish with a twisting motion; on one occasion three sharks were seen attacking an octopus simultaneously in this manner.During mass spawnings of the chokka squid ("Loligo vulgaris reynaudi"), which occur unpredictably year-round but peak from October to December, pyjama sharks deviate from their nocturnal habits and gather in substantial numbers inside the squids' "egg beds" during daytime.
