Tarantulas shed their skin as they grow, like a snake. I have figured out how to take the shed skin and mount it with out killing the spider. This is a photo of one of my spiders shedding.

Below is a photo of one of the two mounted spider skins I have done.

Below is a close-up of the fangs. Looks real doesn't it? That's because it is, and the spider is living happily in her tank. I will be ready when she sheds again.

The finished product is about 2 inches long plus the leg length. My spiders are female Texas Brown Tarantulas.
