Cladoselache is a genus of extinct fish-like shark and is the oldest recognizable shark-like animal. It appeared in the Devonian period.
Cladoselache is thought to have grown up to 6 feet long. It had a very weak jaw joint compared with modern-day sharks, but it compensated with very strong jaw-closing muscles. It has been inferred from its long, streamlined body and deep, forked tail shape that Cladoselache was a fast-swimming predator. Its teeth were multi-cusped and smooth-edged, making them suitable for grasping, but not tearing or chewing. Cladoselache therefore probably seized prey by the tail and swallowed it whole. It was the most primitive of all sharks. Its mouth was unusual and right in the middle of its head.
