In addition, tunics take up only 1% of the squid mantle's wall thickness, whereas the longitudinal muscle fibers take up to 20% of the mantle wall thickness in octopuses. [81] Also because of the rigidity of the tunic, the radial muscles in squid can contract more forcefully. The mantle is not the only place where squids have collagen.

Eat this instead: These fish are very popular and considered a delicacy, but you can get the same texture and feel with U.S. hook-and-line–caught haddock. Orange Roughy AntonyMoran - Getty Images
Many animals considered classic examples of nekton (e.g., Mola mola, squid, marlin) start out life as tiny members of the plankton and then, it was argued, gradually transition to nekton as they grow.
