"Surprising Facts About Alligator Penises That Will Shock You"
Researcher Brandon Moore of Louisiana Tech University had a surprise when dissecting an alligator and accidentally triggered an erect penis, which stays permanently erect due to layers of collagen. Unlike mammals and birds, the alligator penis doesn't need to inflate and is tucked behind a cloaca until needed. This unique feature allows for quick fertilization before being retracted. Other animals, like blue whales, also have unusual reproductive organs, with penises up to 10 feet long and testes weighing up to 150 pounds.
