Young European Cuttlefish (IMAGE)
Caption
A young European cuttlefish (Sepia officinalis) trying to escape predation by expressing dermal papillae in 3-D and a mottled pattern, both of which disrupt the body contour and allow the cuttlefish to fool predators by avoiding recognition. As reported by Gonzalez-Bellido et al., these muscular structures contain a mix of muscle types that allow the animal to express and flatten the papillae quickly, and to maintain papillae expression for extensive periods without the need for neural input. The circuit that controls them appears homologous to the squid skin iridescence circuit.
