Questions & Answers

Q: How does a chameleon's tongue work?

A chameleon's tongue works by using a series of sphincter muscles to squeeze the tongue muscle off of the protruding bone, propelling it forward to catch prey.

Q: What is diaphonization?

Diaphonization is a process that allows scientists to see the bones and structures of a specimen by clearing the tissue and staining the bones.

Q: Does the hyoid bone in a chameleon work like a mechanical bar linkage?

Yes, the hyoid bone in a chameleon operates similarly to a mechanical bar linkage, allowing the chameleon to control the movement and extension of its tongue.

Q: What other animals does Mojo, the chameleon, eat?

Mojo eats a variety of insects, including crickets, hornworms, cicadas, butterflies, and moths.

Summary & Key Takeaways

• Chameleons have a specialized tongue that can be launched forward to catch prey thanks to a series of sphincter muscles.

• The chameleon's tongue is propelled by a longitudinal bone, which is fired by the hyoid bone located in the back of the throat.

• Diaphonization or clearing and staining techniques allow scientists to see the intricate structures of a chameleon's tongue and throat.
