Do Hatchling Cuttlefish Learn Camouflage or Inherit It?
European cuttlefish emerge from their eggs equipped with a near-complete vocabulary of adult camouflage patterns rather than learning the skill through trial and error. Recent neurobiological studies reveal that while their neural pattern-matching software is built-in at birth, young cuttlefish gradually upgrade their camouflage resolution as new pigment cells mature over time.
