Q:

What are the contents of a frog's stomach?

A:

Quick Answer

Frogs may contain a variety of foods in their stomachs, including insects, mollusks, worms, arachnids, amphibians, reptiles, rodents, birds and fish. Frogs swallow their prey whole, so it is often possible to identify their recent prey items upon dissection. Most frogs used for dissections are medium-sized species that prey primarily on insects, arachnids and other frogs, but occasionally one is found to have swallowed a fish or snake.

Full Answer

Frogs primarily rely on their vision to find prey, and they often fail to notice prey that does not move. Scientists studying the prey-capturing habits of leopard frogs have found that while frogs can see insects that are 90 degrees to their right or left, they prefer to capture prey that is in front of them. However, frogs sometimes attempt to capture prey to either side, and some individual frogs demonstrate a preferred side.

While some frogs actively forage for food, the vast majority simply wait motionlessly for prey to come within range. Once the prey is close enough, frogs open their mouths and extend their tongues. Covered in sticky mucus, the tongue ensnares small prey. When attacking larger prey, the frog's arms are sometimes used to help force the animal into its mouth.

  • Q:

    How has a frog adapted to its environment?

    A:

    Different frogs have different adaptations, but generally frogs have eyes on the top of their head for seeing out of the water, a long, sticky tongue for capturing prey such as insects and sensitive skin for absorbing water and oxygen. According to BioWeb ULAW, many frogs such as the Northern Leopard Frog have powerful legs that help them adapt to their environment both by jumping in a zigzag pattern to avoid being eaten on land, and also for swimming skilfully enough to catch their own prey in water.
