There are about 800 species of cephalopods; a group that includes the octopuses, squids, cuttlefish, and chambered nautiluses. This is an important group in that they serve as a food source for humans and other animals, are popular display animals, and are frequently employed in a variety of research applications. Their acute vision, dexterity, and intelligence make them fascinating animals to observe and study. In Great Britain an Institutional Animal Care and Use Committee (IACUC) application is required to perform research on cephalopods, largely due to their sentience (Mather and Anderson 2007). Unfortunately, most species are short‐lived in the wild and captivity. Common problems in captivity include trauma, anorexia, microbial infections, and water quality challenges (Hanlon and Forsythe 1990; Sherrill et al. 2000; Scimeca 2012).

There is not a lot of published information on clinical cephalopod surgery. Harms et al. (2006) describe surgical excision of fungal granulomas from a cuttlefish (Sepia officinalis) mantle. They did not use any surgical scrub for fear of damaging the sensitive skin or inducing toxic effects on the circulating anesthesia water. A 5 mm diameter wound was closed with 4‐0 polyglyconate on a taper needle using a simple continuous pattern. A larger (3 x 4 cm) wound was closed using the same suture and needle with an interrupted cruciate pattern.

A fairly large body of literature exists regarding research surgical procedures in cephalopods, particularly octopuses, but most of the surgeries are short and apply to amputation and destruction of organs and tissues in order to study behavior, regeneration, and behavioral and physiologic responses (Wells and Wells 1975; Wells 1980; Andrews et al. 1983; Sumbre et al. 2001; Fossati et al. 2013).
