They catch their prey by using the end of their two long tentacles. A taxonomy of the movement possibilities for any species, within the constraints of its neural and skeletal systems, should be one of the foundations of the study of its behaviour. These animals are social creatures often found in small groups that communicate through a variety of complex signals. Experimental support for squid ink acting as a conspecific alarm cue has recently been provided for Caribbean reef squid (Wood et al., 2008).
