Check out the size of the pectoral fins in front, and how far back the the dorsal fin is.

I thought that too at first, but your looking at the belly only. The picture is of a 3 foot dogfish. It is the only kind of shark that lacks anal fins.

Ok... I see the perspective now. But I also see an anal fin. I circled it in red.
