Our brachypelma Smithi tarantula molted about a week and a half ago. Tonight my seven year old daughter went into hysterics because she found our pet on his back with his legs curled in. We thought he was dead. We opened the enclosure and he jumped up and moved. Can someone enlighten us on what the heck he was doing? We have since looked up what a death curl looks like and this wasn’t it. Is this a thing....tarantulas laying on their backs? Any insight on this is welcomed!
