Two live Pacific spiny dogfish sharks.

Contrary to what popular media portrays, we actually don’t know much about what sharks eat. Even less is known about how they digest their food, and the role they play in the larger ocean ecosystem.

In a rapidly changing Arctic, one area might serve as a refuge — a place that could continue to harbor ice-dependent species when conditions in nearby areas become inhospitable.
