Coelacanths are the only living vertebrates with a jointed skull. This allows them to open their powerful jaws widely and deliver a strong bite, enhancing their ability to catch and consume prey effectively.
Once believed to have gone extinct with the dinosaurs 65 million years ago, this ancient group of fish has a fossil history stretching back 360 million years. Today, only two living species remain, living in deep waters up to 700 m below the surface.

Coelacanths are the only living vertebrates with a jointed skull. This allows them to open their powerful jaws widely and deliver a strong bite, enhancing their ability to catch and consume prey effectively.
Coelacanths are nocturnal, slow-moving drift hunters that conserve energy by passively floating and waiting for prey to pass by. This low-energy hunting strategy is effective for ambushing prey such as cephalopods and fish. When needed, coelacanths can move swiftly to capture prey or escape potential threats.
All extant species of coelacanths are endangered and protected under the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES)—the international agreement that helps safeguard wildlife from overexploitation.
