TRIVIA 0000008: Did you know that Iguanas, koalas and Komodo dragons all appear to have two penises? To clarify, though, they have a single penis, but it is split in two (pretty much ‘Y’-shaped.) This organ is known as a hemipenes. Snakes also share this interesting feature. Apparently, the dual penis is for ease of left-handed or right-handed mating. Also, at least in snakes, the semen does not flow through a vessel (like in mammals), but rather, a groove.” Male humans have that also rare penile disorder known as “diphallic terrata” or “two penises”.
