One of my Grammostola rosea tarantulas molted yesterday and I was lucky enough to witness it. The last few times my tarantulas molted, I had to leave for class or work and missed the most interesting aspect of it. This time around I got some great photos.

Tarantulas and all other invertebrates who molt to grow don't gain their regular colouration until after their new exoskeleton expands and hardens. That's why this spider appears to be so different in colour from the exoskeleton from which it pulls itself.

Even its fangs are soft and white, and it's extremely vulnerable at this stage until its exoskeleton does harden again. In the last photo, its completely free from the exuvia, and stretching its legs. Ah the wonders of nature! Cheers!


  1. oh my neat to see! thanks for sharing long does this process take?

    1. they'll lay on their back for up to a few hours, but once they crack their old exoskeleton it's pretty quick, this guy was back on its feet within an hour of starting the whole process
