This chapter focuses on the characterization of the squid olfactory system in terms of morphology, behaviour, and electrophysiology. There have been many discussions regarding usage of the specific vertebrate-oriented labels of “taste” and “olfaction” in relation to the various chemosensory systems of invertebrates, especially marine and aquatic species. One classification scheme suggests that contact chemoreception, which can often be mediated by receptors distributed over a large portion of the body, can be considered the aquatic equivalent to taste, whereas chemoreception of dissolved chemicals originating from a distant source falls into the category of olfaction. Squid are predatory animals with highly developed visual, vestibular, auditory, and tactile systems. They are also prey for fish and marine mammals. To avoid predation, squid have developed a very effective escape-jetting response. Although escape jetting is an alarm response, it is not clear to what degree the squid perceive danger by visual, tactile, auditory, and chemical cues. The anatomical descriptions of a putative olfactory organ in cephalopods first appeared in early literature, but it has only recently been shown that squid have chemosensory capabilities.
