When it is time to mate, frogs assemble at a body of water. Males arrive first and call females to the site. In the reproductive act, the male mounts the female and fertilizes the eggs as the female releases them. In some species, the adults then abandon the eggs.Continue Reading
One type of breeding, known as prolonged breeding, involves frogs assembling annually at lakes, streams or ponds. Often, large numbers of frogs migrate back to the bodies of water where they were conceived and became larvae. In such cases, males acquire territories they defend from other males. When croaking to attract females, larger frogs tend to have deeper voices than smaller frogs, and these draw females more easily than younger, smaller frogs. Sometimes, males known as satellites wander without territory and intercept females or take over territories abandoned by exhausted calling males.
Some species are considered explosive breeders and converge on suitable breeding pools when one is found by a male. In these cases, the frogs croak in unison to create a very loud noise. Sometimes conditions may not be right, and frogs may go two to three years without mating.
Once the eggs are fertilized, they float freely, become attached to plants or sink in the water. Tadpoles hatch from the eggs within a few days to a week. Depending upon the species, within a few months to a few years, the tadpoles fully metamorphose into frogs, developing lungs and limbs, losing their tails, and altering their jaws and digestive systemsLearn more about Frogs
Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.Full Answer >
To get rid of frogs, remove all available water sources on the property, reduce damp vegetation, such as thick underbrush, and place frog traps made with PVC pipe in the affected areas. It is illegal to disturb endangered frog species that are legally protected.Full Answer >
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.Full Answer >
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.Full Answer >
