Flashcards

Chondrichthyans

A class of jawed fish with skeletons primarily made of cartilage.

Cartilaginous Skeleton

In Chondrichthyans, the cartilaginous skeleton evolved secondarily; their ancestors had mineralized skeletons.

Sharks, Rays, and Skates

The most diverse group of Chondrichthyans, characterized by their cartilaginous skeletons.

Study Notes

Chondrichthyans skeletons' are composed primarily of cartilage.
Cartilaginous skeletons evolved secondarily from an ancestral mineralized skeleton.
The largest and most diverse group of chondrichthyans includes sharks, rays, and skates.
