Scientists Decode Unique Endangered Fish Genome
Scientists have for the first time sequenced the mitochondrial DNA of the Brahmanakenda fish found solely in Kerala’s Periyar Tiger Reserve. The breakthrough offers insights to protect this critically endangered species.
Introducing Lepidopygopsis typus
Lepidopygopsis typus, locally dubbed Brahmanakenda, is a monotypic freshwater fish occupying cold streams in the Western Ghat mountains. Monotypic species with no close relatives have high evolutionary importance.
Brahmanakenda is categorized as endangered by the IUCN Red List due to its limited habitat and threats from invasive fish. Decoding its genome is an urgent conservation priority.
Mitochondrial Genome Findings
The mitochondrial genome helps elucidate a species’ evolution and differentiation from relatives.
Key revelations include:
- Genetic adaptations allowing survival in chilly uphill waters
- Distinct genomic structure differing from other regional fish
- Specific mutations likely contributing to endangerment
Conservation Implications
Researchers say Brahmanakenda represents an EDGE species that is both Evolutionarily Distinct and Globally Endangered.
The relic fish’s one-of-a-kind genome offers living evidence of the Western Ghats’ evolutionary past.
But its precarious state and unusual genetics necessitate swift habitat protection policies before this aquatic heritage disappears.
