It takes around 2-3 weeks for the fertilized eggs to develop. The newly hatched miracidia will swim rapidly to search for its primary intermediate host (Planorbella trivolvis). [3] The first intermediate host is the ram's horn snail. The second intermediate hosts are fish and larval amphibians including frogs and salamanders.
Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history.
The temnospondyl Eryops had sturdy limbs to support its body on land Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing Japanese giant salamander (Andrias japonicus), a primitive salamander The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species Wallace's flying frog (Rhacophorus nigropalmatus) can parachute to ...
The numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, [12] of which nearly 90% are frogs. [ 13 ] With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart ...

[56] [57] Spring peeper, Pseudacris crucifer [58] [59] Spring peepers are very common in Vermont. [60] Wood frog, Lithobates sylvaticus [61] [62] Wood ...
Carpenter frogs are recognized by their call which resembles a carpenter hammering, which gives them their name. They have ectothermic, heterothermic and bilateral symmetry. The frog's throat pouch is spherical shaped when inflated. Full grown frogs are medium-sized 4.1-6.6 centimeters. [3]
While only the skull - measuring around 1.2 inches (3 cm) long - was discovered, the researchers think Kermitops had a stoutly built salamander-like body roughly 6-7 inches (15-18 cm) long, though ...
On the other hand, Amphibian Species of the World 6.0, an online reference, uses Lithobates as a genus. [1] This definition is also followed by, e.g., the International Union for Conservation of Nature (IUCN) [12] and the Society for the Study of Amphibians and Reptiles. [13]
