Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs ...

Roughly half of all frog species have a life cycle that starts with eggs laid in water, which hatch into aquatic tadpoles, and then go through metamorphosis and become adult frogs.

This robot trio mimics the life cycle of a frog Search-and-rescue operations could one day feature a fleet of frog-bots to help save the day.

It's a celebration of all things frog, from their history to their staggering diversity to the life cycle that takes them from egg to tadpole to adult.
