Euteleostomi

Euteleostomi is the largest group of vertebrates. Except for hagfish, lampreys, and cartilaginous fishes all vetebrates are part of this group. All Euteleostomi have a skeleton made of bone,^[2] and a skull. In the case of several fish related to the sturgeon, most of the skeleton has again been transformed to cartilage.
