How do frogs fertilize eggs?
In most frog species, fertilization is external. The male frog grabs the female’s back and fertilizes the eggs while the female frog releases them (Figure 2.2B). The pronucleus of the egg and the pronucleus of the sperm will meet in the cytoplasm of the egg to form the diploid zygotic nucleus.
Do frogs come back to the same pond every year?
To respond. Amphibians tend to return to the same pond every year – chances are there has been a pond present that the animals are looking for. Amphibians migrate to ponds in the spring, often returning to areas where they spawned in previous years.
Will the tadpoles die if the water dries up?
Tadpoles are branchial respirators, they have gills and must therefore draw their oxygen from a liquid medium, water. They don’t work well enough to exchange oxygen and carbon dioxide with the air, and so the tadpoles suffocate when taken out of the water.
Is it illegal to take tadpoles from a pond?
To respond. It is not illegal to keep tadpoles, just be sure to provide them with the right conditions and release the froglets where you found the spawn. You can buy a guide on how to raise tadpoles from our Froglife shop. Keeping common frog or common toad tadpoles in captivity is not illegal.
What will kill the tadpoles?

Roundup herbicide is deadly to some species of tadpoles, says a University of Pittsburgh researcher who tested the compound in experimental tanks.
Do the frogs come back to the same place?
Frogs tend to return to the same location to breed each year, but they are obviously adaptable, increasing their chances of survival by laying eggs in any suitable location. Create a shallow pond in the garden or woods and the frogs will likely find it and lay eggs.

Why do frogs stick together?
When you walk in the evening near a pond, river or large puddle, you can see two frogs clinging to each other. This is a behavior called amplexus: it allows the male frog to place its cloaca close to that of the female in order to fertilize its eggs.

Which frog lays eggs on its leaves?
ebraccata, a small tree frog from Central America, lays its eggs in a single layer on the upper surfaces of horizontal leaves, a few centimeters above the pond. Upon hatching, the tadpoles wriggle to the edge of the leaf and drop into the water.
What drives a female to release eggs?
Answer: Estrogen is highest in females captured in amplexus when they are likely closest to spawning. At this stage, the receptivity is the highest and the selectivity the lowest. Estrogen, along with both behaviors, drops after the eggs are released.
Are there male and female frogs?
