Wild & Weird: Millipede Feet Facts
Although the word millipede comes from the Latin for "a thousand" and "foot," there's a bit of inflation in that name: These crawly critters don't really have 1,000 feet. The count varies from under 100 to a few hundred, depending on the number of an animal's body segments.
Newborn millipedes have a measly three pairs of legs — they grow the rest later. The fossil record suggests that, as some of the planet's first air-breathers, these invertebrates may be the oldest animals to have exited the ocean's primordial soup in favor of land.
Male millipedes have several specialized "sex legs" called gonopods, which they use to transfer sperm packets to females.
