How many rows of teeth does a spiny dogfish shark have? What depths do they dwell in?
Question Date: 2015-05-09
Answer 1:

The spiny Dogfish has 28 upper teeth and 22-24 lower teeth. They live at depths up to 2950 feet! Here is the website where I found this information and you can see a drawing of the teeth: dogfish teeth

It appears that it has two rows of teeth; one is sharper and the other is more dull and used for grinding.
