Anatomy of a wood frog tadpole (Lithobates sylvaticus) As a frog tadpole matures it gradually develops its limbs, with the back legs growing first and the front legs second. The tail is absorbed into the body using apoptosis. Lungs develop around the time as the legs start growing, and tadpoles at this stage will often swim to the surface and ...
Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. [2] Its name refers to the very large—up to 27 cm (11 in) long—tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length.
Tadpoles are typically herbivorous, feeding mostly on algae, including diatoms filtered from the water through the gills. Some species are carnivorous at the tadpole stage, eating insects, smaller tadpoles, and fish. The Cuban tree frog (Osteopilus septentrionalis) is one of a number of species in which the tadpoles can be cannibalistic ...
The tadpole of this species is considered unpalatable to many species that would commonly predate on tadpoles. They also exhibit behaviors to avoid predation. To avoid fish, the tadpoles will move to stream margins in order to make them inaccessible to the fish. The tadpoles will also reduce activity after sensing a fish's chemical cues. [21]
Tadpoles probably spend most of their time attached to such substrates by a large oral sucker. The large, sucker-like mouth parts of the tadpoles are a second distinctive feature of the species, enabling survival in turbulent water unsuitable for other frogs. They prefer turbulent water to smooth, swiftly flowing water. [16]
The microhylids of New Guinea and Australia completely bypass the tadpole stage, with direct development from egg to frog. The arboreal species can therefore lay the eggs within the trees, and never need venture to the ground. Where species do have tadpoles, these almost always lack the teeth or horny beaks typical of the tadpoles of other ...
The male and female great barred frog will enter the water for amplexus. After laying the eggs, the female will flick them onto the bank for development. The eggs will then be washed into the stream or pond after the first rain and hatch into tadpoles. The tadpoles take around 12 months to develop into frogs. [2]
Clawed frogs are carnivores and will eat both living and dead prey, including fish, tadpoles, crustaceans, annelids, arthropods, and more. Clawed frogs will try to consume anything that is able to fit into their mouths. Being aquatic, clawed frogs use their sense of smell and their lateral line to detect prey rather than eyesight like other frogs.
