Frogs, on the whole, are carnivores which mean they usually eat other creatures. They are not picky eaters. The smaller frogs usually eat insects, spiders, bugs and worms. The bigger ones will even go for mammals that are smaller than them like a mouse, little chicks, small birds, snails, slugs, centipedes, rats, bats, small fish and even other frogs. However, most frogs do like they food alive and moving. Anything dead will not end up as their food.
How do frogs catch their prey?
Frogs do not go around chasing their prey. Instead, they sit motionlessly, watch and wait for the prey to come close enough and then jump forward and flick out their sticky tongue to grab it at an extremely fast speed. They then swallow their prey whole because they cannot chew. Notice how frogs blink or close their eyes when they eat, This is because they eyes sink through the openings in the skull to help push the food down the throat.
What about those which have no tongues? Yes, there are frogs that do not have tongues. These tongueless ones use their fingers to catch their prey. Some examples of tongueless frogs are the Surinam toads, the common clawed frogs, dwarf clawed frogs, Merlin’s clawed frogs and tropical clawed frogs.
A frog will vomit out any food it does not like or is poisonous. It will avoid that food in future.
