Cochliodus is a noun that refers to a genus of extinct cartilaginous fish that existed during the Carboniferous and Permian periods. This genus belonged to the group known as the holocephalians or ratfish, which are characterized by their cartilaginous skeletons, tooth plates, and specialized gills.
Cochliodus had a unique appearance, resembling a flattened shark-like fish with a prominent snout and large expressive eyes. It typically ranged from about 10 to 30 centimeters in length. Fossilized remains of Cochliodus have been found in marine sediments throughout Europe, North America, Africa, and Asia.
These ancient creatures were primarily bottom-dwellers, inhabiting shallow coastal waters and lagoons. They were opportunistic feeders, using their specialized tooth plates to crush shells and prey on small invertebrates such as mollusks and crustaceans.
Cochliodus played a vital role in the marine ecosystems of the Carboniferous and Permian periods, serving as both predator and prey. Their fossilized remains serve as important indicators for paleontologists, helping them to understand the ancient environments and ecosystems in which they existed.
Overall, Cochliodus is a significant genus of fish that provides invaluable insight into the evolutionary history and biodiversity of ancient marine ecosystems.

The word "cochliodus" has its etymology rooted in the Greek language. It is derived from the combination of two Greek words: "kóchlias" meaning "spiral" or "coil", and "odós" meaning "tooth". Therefore, "cochliodus" can be translated to mean "spiral tooth" or "tooth with a coil". This name was given to a genus of extinct cartilaginous fish that lived from the Late Devonian period to the Early Permian period.
