Breviceps is a genus of frogs in the family Brevicipitidae. Species in the genus Breviceps are commonly known as rain frogs or short-headed frogs. [1] [2] They occur in arid to semiarid climates of Eastern and Southern Africa. [1]

Taxonomy

The genus Breviceps consists of 20 species, of which most occur in southern Africa. There are five species found in the Western Cape, B. gibbosus , B. fuscus (black rain frog), B. rosei (Rose's rain frog), B. montanus (mountain rain frog) and B. acutirostris (strawberry rain frog). Two species are found in arid areas and other species are found in the eastern and northern parts of southern Africa. [3]

Description

Species of the genus Breviceps are sexually dimorphic: males are much smaller than females. [2] This prevents normal amplexus; instead, males and females produce an adhesive secretion from the skin that allows them to "stick" together during mating. [2] [4]

Ecology and behaviour

Species of the genus Breviceps spend most of the year underground; even when on the surface, they are inconspicuous because of their slow movements and cryptic colouration. They walk rather than hop. They are able to burrow rapidly, backwards, into the soil by using the enlarged, spade-like metatarsal tubercles on their feet. [4]

These frogs emerge after rain to feed on small arthropods such as ants, termites, beetles, moths, woodlice, amphipods, juvenile millipedes, and caterpillars hence the name rain frogs. Reproduction also occurs during the rainy season. Choruses start immediately after heavy rains, although this may be delayed in colder areas. Eggs are laid in chambers below the surface of the soil, rocks, or fallen logs. After hatching, the movements of the tadpoles make the remains of the egg mass into a froth. The female remains close to the egg chamber until the tadpoles are fully developed. [4]

A tadpole or polliwog is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically.

<i>Breviceps acutirostris</i> Species of amphibian

Breviceps acutirostris, also known as common rain frog, strawberry rain frog, or Cape short-headed frog, is a species of frog in the family Brevicipitidae. It is endemic to the southwestern Cape region in South Africa. It is a burrowing frog that lives in fynbos heatland and forests at elevations below 1,600 m (5,200 ft) above sea level. Development is direct . It is threatened by habitat loss, although much of its habitat is also protected.

<i>Breviceps adspersus</i> Species of amphibian

Breviceps adspersus, also known as common rain frog, bushveld rain frog, and many other vernacular names, is a species of frog in the family Brevicipitidae. It is found in Southern Africa, in Angola, Democratic Republic of the Congo, Namibia, Botswana, Zambia, Zimbabwe, South Africa, Eswatini, and Mozambique.

<span class="mw-page-title-main">Bilbo's rain frog</span> Species of amphibian

Bilbo's rain frog is an amphibian species in the family Brevicipitidae, endemic to South Africa. The frog was named after Bilbo Baggins, the main character from The Hobbit by J.R.R Tolkien. The frog was named as such because the scientist who discovered it used to read the novel to his children. Its natural habitats are temperate grasslands and edges of wood plantations, wherein it spends most of its time in its burrow. The species is threatened by construction, maintenance of roads, silviculture, general habitat degradation/habitat loss, and by road traffic. As a result, it is listed as Near Threatened in the IUCN Red List of Threatened Species.

<span class="mw-page-title-main">Cape rain frog</span> Species of amphibian

The cape rain frog or giant rain frog is a species of frog in the family Brevicipitidae. Adults grow up to 45 mm in length. It was the first African frog species to be scientifically described by Carl Linnaeus in 1758, under the name Rana gibbosa. It is the most common and largest of rain frogs. The name "rain frog" that is applied to the genus refers to a belief that these frogs bring rain.

The desert rain frog, web-footed rain frog, or Boulenger's short-headed frog is a species of frog in the family Brevicipitidae. It is found in Namibia and South Africa. Its natural habitat is the narrow strip of sandy shores between the sea and the sand dunes. This area is characteristic of loose sand and continuous strong winds, with approximately 60mm of annual precipitation and no surface water. It is threatened with habitat loss by such factors as mining and tourism.
