Common toad (Bufo bufo) swimming. Frogs that live in or visit water have adaptations that improve their swimming abilities. The hind limbs are heavily muscled and strong. The webbing between the toes of the hind feet increases the area of the foot and helps propel the frog powerfully through the water.
A few genera such as Pipidae and Microhylidae have species whose tadpoles are filter feeders that swim through the water column feeding on plankton. Megophrys tadpoles feed at the water surface using unusual funnel-shaped mouths. [5] Anatomy of a wood frog tadpole (Lithobates sylvaticus)
Pseudis is a genus of South American frogs (swimming frogs) in the family Hylidae. [1] They are often common and frequently heard, but easily overlooked because of their camouflage and lifestyle, living in lakes, ponds, marshes and similar waters with extensive aquatic vegetation, often sitting at the surface among plants or on floating plants, but rapidly diving if disturbed.
Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole ...
Amietia vertebralis occurs in cold, clear mountain streams of montane grasslands at elevations of 1,600–3,400 m (5,200–11,200 ft) above sea level.It is a water-dependent and largely aquatic species that can stay underwater for long periods (up to 30 hours); [1] during the winter months, it can be seen swimming under ice, [1] although tadpoles can sometimes get trapped in ice. [1]
This shape allows for the production of large forces during swimming through both drag-based and lift-based propulsion. [1] Webbed feet are a compromise between aquatic and terrestrial locomotion. Aquatic control surfaces of non-piscine vertebrates may be paddles or hydrofoils. Paddles generate less lift than hydrofoils, and paddling is ...

Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America .
