Do Fishes have cartilage (Soft Bones) in their tail?
There are two groups of fish, based on their endoskeleton- Chondrichthyes, and Osteichthyes.
1) Fish belonging to the Chondrichthyes group have their endoskeleton made of cartilage. Examples include sharks, rays, etc. These fish have cartilaginous tissues all over their body, including tails.
2) Fish belonging to the Osteichthyes group have a bony endoskeleton. Examples include catfish, sturgeons, etc. The tail of a bony fish is made up of thin, rod-like bones. These bones are joined together to give the tail its flattened shape.
