How does a platypus make its venom?

Platypuses seem like they were put together from other animal’s spare parts. They’ve got a bill like a duck, a flat tail like a beaver, and…venom? What’s up with that? We asked biologist Imogene Cancellare to help us find the answer. Got a question that’s as confusing as platypus anatomy? Send it to us at BrainsOn.org/contact, and we won’t even bill you for the answer! See omnystudio.com/listener for privacy information.
