Adult frogs may live in or near water, but few are fully aquatic. [159] Almost all frog species are carnivorous as adults, preying on invertebrates, including insects, crabs, spiders, mites, worms, snails, and slugs. A few of the larger ones may eat other frogs, small mammals and reptiles, and fish.
Allobates chalcopis is a small frog with males measuring about 17 mm (0.67 in) in snout–vent length and females about 16–18 mm (0.63–0.71 in). Its dorsum is light brown with darker markings. Males have a distinctive, black throat, tapering off to a dark gray, whereas females have uniformly pale orange throat and venter.
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs.
Most anurans in the superfamily have a lateral‐bender which is a type of pelvis morphology found in walking, hopping and burrowing frogs. Some species that appear later in the taxon have a sagittal‐hinge pelvis found in aquatic frogs as well as walking, hopping and burrowing frogs and some have a fore–aft slider pelvis found in ...
North America has many species of the family Hylidae, including the gray tree frog (Hyla versicolor) and the American green tree frog (H. cinerea). The spring peeper ( Pseudacris crucifer ) is also widespread in the eastern United States and is commonly heard on spring and summer evenings.
A new species of frog has been officially confirmed, close to 80 years after its existence was first theorized. The frog, Rana kauffeldi, is a type of leopard frog, and the process of establishing ...
Hyla is a genus of frogs in the tree frog family Hylidae. As traditionally defined, it was a wastebasket genus with more than 300 species found in Europe, Asia, Africa, and across the Americas. After a major revision of the family, most of these have been moved to other genera so that Hyla now only contains 17 extant (living) species from ...
The tiny, “cryptic” creature has silver eyes, researchers said in a new study.
