Penises of marsupials and other critters.

Most marsupials, except for the two largest species of kangaroos, have a bifurcated penis. That is, it separates into two separate columns, and so the penis terminates in two ends. The dolphin has prehensile control over his penis, so he sometimes uses it as an sensory appendage with which to probe the ocean floor. The barnacle has the longest penis for its own length: up to twenty times the length of the animal.
