This is an Atlantic Jackknife clam, also known as a razor clam. It's not only delicious in clam strips, but it's also really weird. You may be wondering how a tube-like creature who lives on the floor of the ocean and doesn't have any extremities manages to get around. The answer is much odder than you'd think.

Yes, it kind of looks like a strange penis. Except that it's socially acceptable to boil a razor clam (heyo!).
