Biosphere Update

When I came home, I caught the snail in one of my biospheres extending his siphon to breathe air from the surface. Initially, the siphon extended all the way to the surface of the water, but the snail began to withdraw it when I started shooting video. The snail’s siphon allows it to breathe air from the surface without being caught by a passing bird, it’s a unique feature of the apple snail (Ampullariidae). It’s really amazing how much that little thing stretches, the water surface is about 6″ above the snail.
