Description

Water frog may refer to one of several species of frog:* Species in the genus Pelophylax, widespread in Eurasia, with a few species ranging into northern Africa.* Species in the genus Telmatobius, native to the Andean highlands in South America....

 has greenish-brown skin, speckled with black and yellow flecks, and is well camouflaged as it sits under tree roots or stones. On close inspection it is possible to see that its rather robust body has many small bumps, known as pustules, on the back. The undersides of the legs are orange, and the underbelly and throat are grey. The hind legs are long and slender, suited to propelling the frog through water, and its feet are only partially webbed, indicating that it spends part of its life on land. Juveniles of this species are greener than adults with more yellow flecks.

Range and habitat

Telmatobius espadai occurs only in Bolivia, where it has been found in just two areas: the Rio Miguillas valley near Choquetanga Chico, in the department of La Paz, and near Rio Apaza, in the department of Cochabamba.

, this water frog occurs at 3000–3500 m (9,842.5–11,482.9 ) above sea level. Adults are generally found resting above the water sheltered by tree trunks and stones, whilst tadpoles and juveniles have been found hidden under stones and amongst aquatic plant

Aquatic plants are plants that have adapted to living in aquatic environments. They are also referred to as hydrophytes or aquatic macrophytes. These plants require special adaptations for living submerged in water, or at the water's surface. Aquatic plants can only grow in water or in soil that is...

Biology

Little is known about the biology of this extremely rare species, which is thought to live a partially terrestrial life. The tadpole possesses a large oral sucker, a unique feature amongst Telmatobius water frogs. The function of this sucker has not yet been determined, although it is possible it may help the tadpole cling on to surfaces to prevent it from being swept away by currents, or it could even be used to suck up prey.

Conservation

Telmatobius espadai is now extremely rare; a population census undertaken in 1998 found just one tadpole. This tadpole showed symptoms of chytridiomycosis
Chytridiomycosis
Chytridiomycosis is an infectious disease of amphibians, caused by the chytrid Batrachochytrium dendrobatidis, a non-hyphal zoosporic fungus. Chytridiomycosis has been linked to dramatic population declines or even extinctions of amphibian species in western North America, Central America, South...

, a disease that causes death in frogs and is thought to contribute to declines, and even extinctions, in frog species around the world. There are also significant concerns over the possible effects of a road situated very near to one of the locations where the frog has been located. In addition, various species of water frog are sometimes consumed as part of drink with supposed aphrodisiac
