Cuttlefish

About

How cuttlefish lives

Cuttlefish are intelligent cephalopods that change color and texture while hunting or hiding. A cuttlefish controls buoyancy with an internal cuttlebone. Reef animals thrive in complex habitats where color, shelter, and quick reactions matter.

Conservation

Status and habitat pressure

Stable populations still depend on habitat quality, food availability, and low human pressure. Protecting cuttlefish also depends on keeping coral reef, coast habitats healthy and connected.

Common species still depend on habitat quality, clean water, food webs, and low disturbance.
