Did the Helicoprion exist?

Helicoprion was a bizarre creature that went extinct some 225 million years ago.

Do shark fins grow back?

MYTH: If a shark's fin is cut off, it will just grow back. Sharks cannot actually grow back fins that are cut off. (But some other fish can.) This biological fact is even more troublesome in light of the growing shark fin trade — especially in Asia, where the fins are a key ingredient in a pricey soup.

Should shark finning be banned?

Shark finning is unsustainable. Not only do humans decimate shark populations, but sharks have low reproductive rates, making repopulation difficult. Many types of sharks are exploited for their fins, including endangered species such as the Scalloped Hammerhead and Great Hammerhead.
