Description
The Cuttlefish is a strange and extremely intelligent cephalopod. One of the most successful predators in the ocean, the Cuttlefish has a plethora of unique adaptions, allowing it to consume a wide variety of food. Primarily, it has extremely advanced eyes, capable of spotting and tracking prey with perfect accuracy. Once it comes within range, it can deploy its long feeder tentacles, which shoot out like a pair of tongs to grasp the unwary food item, stunning it and dragging it into this cephalopod's powerful beak. Like many other members of its family, the Cuttlefish is capable of amazing feats of camouflage, altering its skin colour and texture to perfectly blend in with its surroundings-- however, uniquely, it also uses these colour changes to signal other Cuttlefish, allowing an advanced degreed of communication.
