CSIRO scientists Sequenced first full genome of critically endangered ‘Walking’ Australian Spotted handfish

On Oct. 8, 2024, scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency, announced they had sequenced the first ever full genome of the Spotted Handfish (Brachionichthys hirsutus) – critically endangered and endemic to Tasmania. The marine species can be found scuttling or walking along the sands of the Derwent River estuary on its hand-like pectoral fins.

The team was able to sequence the complete genome from a small amount of poor-quality DNA, using what’s called a low-input protocol. This was done in collaboration with the Biomolecular Resource Facility at Australian National University.

Once plentiful around Tasmania’s south-east coast the species’ numbers have dwindled. In 1996, it became the first marine fish listed as critically endangered. Scientists now estimate fewer than 2,000 individuals remain in the wild.
