Dr. Tierney Thys tells us all about the colorful lionfish in this week’s Creature Feature!

When lionfish are young, they have tentacles above their eyes and under their mouths called wigglers. The lionfish uses these wigglers to attract their prey: it wiggles them to get its prey’s attention, and when its prey swims too close, the lionfish will catch it with a super fast strike!

As they grow and become better hunters, the wigglers slowly disappear.

Lionfish also have an amazing survival skill: they are able to slow down their metabolism when prey is less plentiful. They can slow it so much that they can live without food for more than three months!
