 Interaktive Phylogenetic Tree of Sharks -> Order "Bullhead sharks"

The Order "Bullhead sharks"

The order of the bullhead sharks comprises one family with only one genus. There are only 9 known species of bullhead sharks. These bizarre looking sharks possess strong spines in front of both dorsal fins.
As opposed to the other "spine-wearing" group, the dogfishes, bullhead sharks possess anal fins. As their name implies, their heads look very dominant with big ridges above their eyes, and have a broad snout with very large labial furrows. Based on their heterogeneous teeth (their scientific name "hetero-dontus" stands for different shaped teeth) they are considered as primitive group.
Members of this order live only in the waters of the Pacific and Indian Oceans.
