Nannophrys marmorata, commonly known as Kirtisinghe's rock frog or marbled streamlined frog, is a species of frog endemic to Sri Lanka. It used to be placed in the large frog family Ranidae but a phylogenetic study was undertaken using DNA sequences and it is now included in the family Dicroglossidae. [2] [3] Its natural habitats are tropical moist lowland forests, moist montane forests, rivers and streams. It is threatened by habitat loss. [1]

Description

Kirtisinghe's rock frog is a small animal with a broad, short head and rounded snout. The eardrums, visible just behind the prominent eyes, are about half the size of the eyes. The body is stout and the legs are moderately short. The dorsal surface is brown blotched with darker streaks and the ventral surface is pale grey. The legs are transversely banded in dark brown. Kirtisinghe's rock frog grows to a length of about 2.5 cm (1 in). [4]

Distribution and habitat

Kirtisinghe's rock frog is endemic to central Sri Lanka where it is found only in the Knuckles Mountain Range at heights between 200 and 1,200 metres (660 and 3,940 ft) above sea level. It is a semi-aquatic species and is found in and beside fast flowing mountain streams in forested areas, under boulders, in rock crevices and on wet rocks. The tadpoles are also found on rocks in the splash zone near the torrent. [4]

Status

Kirtisinghe's rock frog seems to be declining in numbers and it is listed as "Critically endangered" in the IUCN Red List of Threatened Species. This is because it occurs as several separate populations in a total area of only 100 square kilometres (39 sq mi) and its habitat is being lost because of livestock grazing and tourism, and the streams in which it lives may be being polluted by agrochemicals from tea and cardamom plantations.

Roses ghost frog Species of amphibian endemic to South Africa

The Rose's ghost frog or Table Mountain ghost frog is a species of frog in the family Heleophrynidae endemic to South Africa. It is a medium-sized species with purple or brown blotches on a pale green background and large discs on its fingers and toes. It has a very restricted range, being only known from the slopes of parts of Table Mountain. The tadpoles live in permanent streams but these are in danger of drying up because of the establishment of pine plantations. Because of its small range and changes in its habitat, this frog is listed as critically endangered by the International Union for Conservation of Nature.

<i>Nannophrys naeyakai</i>

Nannophrys naeyakai, also known as the Sri Lanka tribal rock-frog or Sri Lanka tribal rock frog, is a species of frogs in the family Dicroglossidae. It was described as a new species in 2007. It is endemic to Sri Lanka, where it is only known from two localities in Ampara and Monaragala Districts. N. naeyakai can be distinguished from the other Nannophrys species by the details of the tubercles on the fourth toe, sharp and narrow symphysial knob on the anterior edge of mandible and small palmar tubercles. The specific name naeyakai refers to the "naeyaka", spirits of deceased relatives in the believes of Vedda people living in the type locality area.
