Yes, the Singapore freshwater crab (Johora singaporensis) is officially listed as Endangered on the IUCN Red List of Threatened Species. This tiny, endemic crustacean is found only in a few fast-flowing, clean forest streams within Singapore's nature reserves.
The primary threats to its survival include habitat loss due to urbanization, water pollution, and the alteration of stream hydrology. Because its range is extremely restricted and fragmented, even small environmental changes can have a devastating impact on the remaining populations.
Conservationists are working on habitat protection, captive breeding programs, and water quality monitoring to prevent the extinction of this unique species, which has become a symbol of Singapore's freshwater biodiversity.
