When preserved after death, goblin sharks often lose their pink tone and appear grayish.

The goblin shark's distinctive pink coloration results from translucent skin that reveals underlying blood vessels. In life, this gives the animal a fleshy, almost raw appearance.

Unlike reef sharks with countershading camouflage, the goblin shark's pigmentation reflects its deep habitat, where color offers little advantage in darkness beyond light penetration.

The unsettling hue reinforces how deep-sea evolution prioritizes function over familiar aesthetics, producing animals that seem biologically unfinished yet are perfectly adapted to their environment.
