(chon-drich-thy-es): This is another class of fish, but their skeletons are made up of cartilage rather than bone.
Other cartilaginous marine animals include rays, skates, and chimaeras, and they--as well as sharks--are grouped in the class Chondrichthyes

Due to concerns over certain species' status in the wild, these restaurants will also take Chilean sea bass (Dissostichus eleginoides), orange roughy (Hoplostethus atlanticus) and shark (Class Chondrichthyes
, Subclass Elasmobranchi (part)) off their menus.

They all belong to the chondrichthyes
family, whose members lack a bony skeleton.
These special characteristics put sharks into the Class Chondrichthyes
(Chondra means cartilage, oste - bone, and ichthyes - fish).
Spines of the spiny dogfish (Squalus acanthias) have been used to estimate age since the early 1900s (Kaganovskaia, 1933), and the spines of other chondrichthyes
are receiving increasing attention as suitable structures for estimating age and growth (Francis and OMaolagain, 2000; Irvine et al.

A total of 8,793 fish bones were analyzed from the samples in Test Units 1 and 2, representing three Chondrichthyes
(cartilaginous fish) families and 19 Osteichithyes (boney fish) families.
