Fascinating news (in our opinion) about our senior tarantula, Rex. Rex molted for the first time in nearly 4 years! Molting can be very risky, especially for older tarntulas. The most common cause of senior tarntula deaths is getting stuck during a molt. The molting process is extremely taxing for them. After a hunger strike (Rex had a 7 month long hunger strike to prep for this molt!), her body pumps a special lubricating fluid between her new exoskeleton and her old one. Once enough space and pressure has built up, she cracks open the old exoskeleton and very slowly slips herself out of the old shell. Her entire exterior is new - legs, hair, fangs, even her eyes! After successfully escaping the old exoskeleton, Rex lays completely still on her back (a worrying sight!) while her new exoskeleton hardens. During this rest, her body pumps hemolymph (the spider equivalent to blood) from her abdomen out to her legs so she can move them again. Rex laid on her back, completely still, for 30 hours before finally flipping over! Immediately after a molt, tarantulas are soft and vulnerable. The fangs are bright pink and soft after a molt so we must wait a couple weeks for the fangs to harden and turn black again before offering food.
We are happy to report that Rex’s fangs have hardened up and our old girl is an eating machine! After 7 months of no food, you’d probably be pretty hungry too!
This successful molt basically guarantees several more years of Rex time! She should be nearing her 30th birthday the next time she molts! Isn’t Rex the coolest?! Spiders deserve kisses, not squishes. 💋🕷️
