Here is the live shark version of a Russian nesting doll.
University of Delaware's ORB LAB researchers posted this photo of a shark caught eating another shark on Facebook in late July.
ORB via Facebook:
We caught one large female on our first line Friday, but we were not expecting to catch her like this! This unlucky smooth dogfish couldn't resist the menhaden used as bait and unfortunately fell victim to one of the top predators in the bay. The dogfish was about 3 feet long and completely swallowed by the sand tiger shark.
According to ORB LAB, the sand tiger shark was released alive after researchers gave it a small ID tag.
Two sharks, one hook.
