The jellynose fish, also known as the tadpole fish, is a small order of Ateleopodiformes, ray-finned fish of a monotypic species with a single-family Ateleopodidae. Currently, the fish has 12 species in four genera, but these fishes need taxonomic revision. The jellynose fish is deep water and bottom-dwelling marine fish found in the Caribbean Sea, eastern Atlantic, western and central Indo-Pacific, and the Pacific coast of Central America. They are true teleosts because of their cartilage skeletons, although they are not related to Chondrichthyes. They have a large head and bulbous nose with an elongated body. Their tail fins are small except for Guentherus, for whom it is fused with the anal fin, which has 70 rays or more.

What is unusual about jellynose fish?

The jellynose fishes do not have a swim bladder, creating an issue with their buoyancy control since these swim bladders help fish swim. Fishes like sharks have a similar buoyancy issue. To cope with this, they have to use other methods to stop themselves from sinking. To help them with this, they have skeletons made of cartilage that are much less heavy and denser than bones. Also, their enormous livers are packed with fats and oils, keeping their density lower than the seawater.
