How do snakes unhinge their jaws?

“Snakes’ heads are made up of many small bones. Some of these bones, like the ones protecting the brain, are joined together and don’t move. Others have a joint allowing them to move a great deal. Snakes do not have a chin like we do; instead the two halves of the lower jaw are joined by a stretchy ligament. This allows them to separate far apart and for the snake’s mouth to fit around its prey, even if it is wider than the snake’s own head.” Enjoy unlimited visits to ZSL London and Whipsnade Zoos, plus a host of other benefits with ZSL Membership.
