The Western Ghats or the Western Mountain range is a mountain range that covers an area of 160,000 km2 (62,000 sq mi) in a stretch of 1,600 km (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. It is a UNESCO World Heritage Site and is one of the 36 biodiversity hotspots in the world. It is sometimes called the Great Escarpment of India. It contains a very large proportion of the country's flora and fauna, many of which are endemic to this region. According to UNESCO, the Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau and separates the plateau from a narrow coastal plain called Konkan along the Arabian Sea. A total of 39 areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty in Kerala, ten in Karnataka, six in Tamil Nadu and four in Maharashtra.
The brown palm civet also called the Jerdon's palm civet is a palm civet endemic to the Western Ghats of India.
Clinothelphusa kakoota is a species of crab in the family Gecarcinucidae, which is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and rivers. It is threatened by habitat loss, and is listed as a critically endangered species on the IUCN Red List. It is known from a single site with an area of less than 100 km2 (39 sq mi). Its nearest relatives are another Sri Lankan endemic genus of crabs, Ceylonthelphusa.
Parathelphusinae is a subfamily of freshwater crabs, which was formerly placed in the family Parathelphusidae; they are mainly found in South and Southeast Asia, but also found elsewhere in Asia and in Australia
The Gecarcinucidae are a family of true freshwater crabs. The family Parathelphusidae is now demoted to the rank of subfamily, as the Parathelphusinae, within the Gecarcinucidae. "Family" Parathelphusidae is now considered as a junior synonym.
Wildlife of Sri Lanka includes its flora and fauna and their natural habitats. Sri Lanka has one of the highest rates of biological endemism in the world.
Southwestern Sri Lanka rivers and streams is a freshwater ecoregion in Sri Lanka. The ecoregion is listed in Global 200, a list of ecoregions compiled by the World Wide Fund for Nature for conservation priorities. The extensive network of rivers and streams of Sri Lanka drains a total of 103 distinct natural river basins. Several waterfall habitats have been formed as a result of rivers and streams flowing through high and mid elevation areas. The ecoregion spreads over 15,500 km2 in the wet zone of the southwestern part of Sri Lanka. More than a quarter of the freshwater fishes that have been discovered in Southwestern Sri Lanka rivers and streams are endemic. Nine endemic genera of freshwater fishes of Western Ghats and Sri Lanka hotspot Malpulutta are found only in Sri Lanka. Studies suggest that the number of species still to be discovered is quite high. Until recently wetlands in Sri Lanka were used for drainage, construction sites and land fills.
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemic to small areas. As a result, a large proportion are threatened with extinction.
Seychellum alluaudi is a species of freshwater crab endemic to the Seychelles, and the only true freshwater crab in that country. It lives in rainforest streams on the archipelago's granitic high islands. Although it may be abundant, little is known about its biology. If its habitat were to decline in quality, S. alluaudi might become endangered, but it is currently listed as Vulnerable on the IUCN Red List.
Oziotelphusa stricta is a species of freshwater crabs in the family Gecarcinucidae. It is endemic to Sri Lanka. The species was initially categorized as Near Threatened by the finders, but recent observations included to vulnerable by IUCN Red List due to less abundance is observed localities and much restricted ecology.
Kani maranjandu is a species of tree crab first identified in 2017. K. maranjandu has, to date, only been observed in the forests of the Western Ghats in Kerala, India. As of 2021, it is the only species in the genus Kani.
Austrothelphusa transversa(von Martens, 1868), also known as the inland crab, freshwater crab, or tropical freshwater crab is a species of freshwater crab endemic to Australia. A. transversa is the most widely-dispersed species of its genus, as it has adaptations giving it a high tolerance to drought and arid conditions.
Macromia irata is a species of dragonfly in the family Macromiidae. It is endemic to Western Ghats in India.

Ghatiana dvivarna is a species of freshwater crab from the Central Western Ghats in India that was first identified in 2022.
Ghatiana atropurpurea is a species of arboreal crab from India that was first identified in 2016. Unlike other species of its genus, Ghatiana, it is not endemic to the Western Ghats.
Ghatiana splendida is a species of crab from India, first identified in 2016 in the Western Ghats. Tejas Thackeray, among the discovers of the species, has said that "locals" to where it was first described were aware of the species and would refer to it as the "purple tree crab" or the "pink forest crab". Thackeray first encountered the crab while searching for the olive forest snake.
Gubernatoriana is a genus of freshwater crabs, found among the Western Ghats in India.
