Male platypi are also venomous. On other oddity about them, I guess.

Yup. They have a spur on their rear legs that can inject venom. The spur is reminiscent of a rooster's spur, but with a venom gland. Nasty business, and very unmammalian in nature.

A very odd group of animals, the monotremes. Fascinating. I got hooked on them when I first read about them at age 10.
