Detailed explanation-1: -The tailed frogs are two species of frogs in the genus Ascaphus, the only taxon in the family Ascaphidae /æˈskæfɪdiː/. The “tail” in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams.

Detailed explanation-2: -Froglets have fully formed lungs and can be spotted hopping around the edges of the pond. It will not be long until the froglet’s tail is absorbed into its body and finally becomes a frog.

Detailed explanation-3: -The word “salamander” is the name for an entire group, or scientific order, of amphibians that have tails as adults. This includes amphibians commonly known as newts and sirens. Most salamanders look like a cross between a lizard and a frog. They have moist, smooth skin like frogs and long tails like lizards.

Detailed explanation-4: -Tadpoles typically lose about one-quarter of their weight during their transformation into froglets. At 10 to 13 weeks, shortly before the froglet leaves the water in which they have developed, their tail has completely disappeared through the process of apoptosis and their forelegs emerge.
