Cephalopods (squids, octopuses and cuttlefishes) comprise over 800 species, possess advanced nervous, cardiovascular and visual systems, and are masters of camouflage. Sepiadariidae, one family of benthic squids, possess specialized systems of secretion, secreting a viscous slime from their underside. It is believed that these secretions are involved in defending the species, and exhibit unique biochemical and biophysical properties including dramatic volume expansion, adhesion, and antimicrobial defence.
