Frogs

What does a frog eat?
Frogs are carnivores. They eat insects, spiders, worms, snails, fish, and even small rodents like mice.

How does a frog eat?
When a frog spots a tasty meal, it flicks out its long, sticky tongue. The tongue lassos the meal/creature and pulls it back into the frog's mouth.

Do frogs have teeth?
Yes, frogs do have teeth, however,they are small and so not really good for chewing. Frogs mostly use their teeth just to hold their prey in their mouths, and then they swallow their prey whole.

What is so special about a frogs head?
A frog's head has adaptations that help it to swallow prey. Unlike a human's eyes which are fixed in our heads in bony circles called orbits, the orbits surrounding a frog's eyes do not have bottoms. This means that when a frog swallows large prey, it can close its eyelids and drop its eyeballs down into its mouth. Yuck! Then the eyeballs help push the prey down the throat of the frog. (Incredible as it may sound, this is true!)

Not all frogs look or act the same. Frogs have adapted to the environment around them.

A Dyeing Poison Tree Frog is brightly coloured to warn enemies of lethal nerve toxins. Its finger and toe tips have glandular adhesive pads that enable the animal to climb.
