There is no aquatic larval stage and the young develop directly inside the egg.

Unlike amphibians, reptiles do not have an aquatic larval stage.

They have no aquatic larval stage; eggs are laid underneath a stone or log, and young hatch in the adult form.

Early workers concentrated on destroying the immature aquatic stages in their breeding places using what we would now call environmental management.

Hatchlings emerge from the eggs in about three months, having no aquatic stage, like many other salamander species.

Because of this, sirens most likely have evolved from a terrestrial ancestor that still had an aquatic larval stage.

They are holometabolous insects with an aquatic larval stage.

They completely bypass any aquatic stage, so do not have tadpoles.

A tadpole is the aquatic larval stage in the life cycle of an amphibian.

In the last aquatic stage, dark wingpads are visible.
