belong. It is effectively bonding, or how plants and animals hold onto substrates. Adhesion, for Cephalopods, typically happens by means of a pressure system that includes use of the suckers on their and tentacles. Sepia are one taxa of cephalopods that produce a chemical substance to be used for adhesion; the use of this secretion varies depending on each specific animal. In addition, S. tuberculata is one of at least four Sepia species that actually possesses an adhesive structure. No information has been published on whether or not S. tuberculata has the ability to change colors/produce patterns on its body, but the common cuttlefish, S. officinalis, possesses the ability to produce 13 different body patterns composed of a number of different chromatic, textural, postural and locomotor components in its body. The changing of body patterns is primarily used for concealment, and specific patterns are chosen depending on the strategy the cuttlefish intends to use be that disruptive coloration or general color resemblance .
