Abstract

Cannibalism refers to the action of con- suming a member of the same species and is common in many taxa. This paper reviews the available literature on cannibalism in cephalopods. All species of the class Cephalopoda are predators and cannibal- ism is common in most species whose diet has been studied. Cannibalism in cephalopods is density- dependent due to their aggressive predatory and in case of the octopuses territorial nature. It also depends upon local and temporal food availability and of the reproductive season. Cannibalistic behaviour is pos- itively related to the size of both cannibal and victim. It can affect population dynamics of cephalopods in periods of low food availability and/or high popula- tion abundance. Cephalopods are generally restricted in their ability to store energy. It is thus assumed that cannibalism is part of a population energy storage strategy enabling cephalopod populations to react to favourable and adverse environmental conditions by increasing and reducing their number. Finally, we propose five orientation points for future research on cannibalism in cephalopods.
