This is the third in the FAO series of worldwide annotated and illustrated catalogues of major groups of organisms that enter marine fisheries. The present volume includes 173 cephalopod species of actual or potential fishery interest, belonging to the Nautiloidea (nautiluses), Sepioidea (cuttlefishes), Teuthoidea (squids) and Octopoda (octopuses).
Squids use a diverse range of body patterns for communication. Each pattern consists of a series of chromatic, postural, and locomotor components that are under neural control and can change within fractions of a second. Here we describe an ethogram of 48 body pattern components from in situ observations of reproductively active Sepioteuthis australis.
