The African butter catfish is a species of fish in the family Schilbeidae. It is native to many major river systems in Africa. Other common names for the fish include butter fish, butter barbel, African glass catfish, lubangu, mystus catfish, silver barbel, and silver catfish. It was originally described as Silurus mystus by Carl Linnaeus in 1758.
Ceylonthelphusa is a genus of freshwater crabs endemic to Sri Lanka, where they live in moist lowland forests, swamps and rivers. Many of the species are on the IUCN Red List of threatened species, with the greatest risk factor being habitat loss. Ceylonthelphusa contains these species:
Mahatha is a genus of freshwater crabs endemic to Sri Lanka. Four of the six species are critically endangered due to habitat loss, and two are listed as Least Concern on the IUCN Red List.
Oziotelphusa is a genus of freshwater crabs in the family Gecarcinucidae. Its members are found in Sri Lanka and southern India. The genus was formerly placed within family Parathelphusidae, but now it is accepted that Parathelphusidae is the junior synonym of Gecarcinucidae.
Perbrinckia is a genus of freshwater crabs of the family Gecarcinucidae that is endemic to Sri Lanka, named after Per Brinck. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and rivers. It contains 14 species, most of which are included on the IUCN Red List as critically endangered species (CR) or vulnerable species (VU) because they are threatened by habitat loss; only one species is of least concern (LC).

Bagarius bagarius, also known as the devil catfish, dwarf goonch or goonch, is a species of catfish in the genus Bagarius. It is generally reported as being found in large and medium rivers in South Asia, and is likely synonymous with B. yarrelli.

Mystus vittatus, the striped dwarf catfish, is a species of catfish of the family Bagridae. It is found in brackish water systems with marginal vegetation in lakes and swamps with a mud substrate of Asian countries Pakistan, India, Sri Lanka, Nepal, Bangladesh and probably Myanmar. Populations of Southeast Asian countries is in debate, due to close morphological similarities among Mystus species in that region.
