chondrichthyes
/ˌkɒndrɪkˈθaɪ.iːz/Class of fishes with primarily cartilaginous skeletons
From Greek chondr- (Cartilage or gristly tissue) + Greek ichthy- (Fish).
Word Ancestry
Picture a shark’s skeleton: not a bony framework like ours, but a springy internal scaffold of cartilage, the same flexible material found in your ears and nose. That is exactly what the name Chondrichthyes announces, joining Ancient Greek χόνδρος, “cartilage,” to ἰχθύς, “fish.” The second root has had a remarkably busy scientific afterlife: ichthyology is the study of fish, while an ichthyosaur was a fish-shaped marine reptile whose name literally means “fish-lizard.” In the nineteenth century, zoologists turned these Greek building blocks into a formal class name for sharks, rays, and chimaeras, setting them against Osteichthyes, the “bony fish.” Remember the contrast as a tiny Greek signpost: chondr- bends, ichthy- swims.
