Quick Answer

Frogs reproduce through eggs, which they lay in the water. These eggs hatch into tadpoles that later grow into adult frogs.

There is also a species of tree frog that uses nests that are built into the water so that the tadpoles are born directly in the water. A large group of frog eggs are called frog spawn because they have a gooey, slimy material connecting them together. The frog uses the gooey material to help the eggs reach the surface of the water because the material floats. Female frogs lay between 10,000 and 20,000 eggs.

Once the egg has hatched into a tadpole, then the tadpole has to go through the process of metamorphosis, which turns it into an adult frog. The exact length it takes for metamorphosis to complete depends on the frog species. Most frogs will need several weeks up to a year for the metamorphosis process. Some frogs need more than a year.

The lifespan of a frog is typically 7 to 9 years, but frogs can easily be eaten by predators such as lizards, birds and snakes. Frogs eat insects, fish, mice and even birds depending on what the frog species can fit into its mouth.

  • Q:

    How do frogs breathe underwater?

    A:

    Adult frogs breathe through the skin when under water. They have thin skin, which has a massive network of blood vessels and capillaries under it. Oxygen enters the frog’s body through the skin and goes into the blood stream, which carries it to the rest of the body. Once the blood cells have released the oxygen, they absorb carbon dioxide and carry it back to the skin for excretion.

    What adaptations permit the frog to live on land and in water?

    A:

    One of the adaptations that allow frogs to live on land and in water is their permeable skin, which allows them to absorb water from their surroundings. However, if the frogs are trapped away from water for a significant length of time, this may cause them to desiccate. To help prevent this from happening, frogs produce a mucus coat, which retards the rate of evaporation.

  • 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.
