Among marine molluscs, some
cephalopods, such as small paralarvae (e.g., young pelagic squids; Young & Harman 1988) that have been chemically preserved while alive typically remain in the ball posture (Young 1972, Goto 2005).

Like other
cephalopods, cuttlefish possess well-developed vision; therefore, they must perceive particular visual information from prey and then initiate hunting behavior, in a manner similar to a typical reaction to the sign stimulus reported in other animals.

If this is indeed a happy note in a time of generally bad news for marine life, I for one welcome our new
cephalopod overlords.
Led by James Pikul and Robert Shepherd, the team's pneumatically-activated material takes a cue from the 3D bumps, or papillae, that
cephalopods can express in one-fifth of a second for dynamic camouflage, and then retract to swim away without the papillae imposing hydrodynamic drag.
This exciting and extremely rare intertidal encounter has prompted a formal report on the sighting and also an overview of the biology of this species and of
cephalopods more generally.
Cephalopod remains (whole beaks, beak fragments, and eye lenses) and fish remains (bones and eye lenses) were preserved in 50% isopropyl alcohol and fish otoliths were stored dry.
The moderately expanding shell of the Early Ordovician
