Using its fins to walk rather than swim along the ocean floor, the pink handfish is one of nine newly named species described in a recent scientific review of the handfish family. This remarkable fish, measuring about four inches (ten centimeters), has only been spotted four times, all in areas around Hobart on the Australian island of Tasmania.

After not being seen since 1999, the pink handfish was recently identified as a unique species. This formal classification came after extensive research that considered various factors such as vertebrae and fin ray counts, coloration, scale and spine presence, and proportional body measurements. Daniel Gledhill from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) led this review, emphasizing the need for further study on these poorly understood fish.

Recent Sightings and Conservation Status

In a surprising turn of events, a pink handfish was spotted for the first time in over two decades during a joint survey by Parks Australia and the University of Tasmania in December 2021. The fish was filmed at a depth of approximately 120 meters in the Tasman Fracture Marine Park, marking a significant discovery for marine biologists. Prior to this sighting, the species had been declared endangered due to its rarity and limited distribution[1][2][3].

The recent sighting has reignited hope for the survival of the pink handfish, suggesting it may inhabit a wider range than previously believed. This finding is critical as it highlights the importance of collaborative research efforts in managing marine ecosystems[1][6].

Habitat and Ecological Importance

All known species of handfish are found exclusively in shallow coastal waters off southeastern Australia. The pink handfish’s habitat is characterized by underwater canyons and rocky reefs that support a unique diversity of marine life[1][3]. Despite their fascinating adaptations for life on the ocean floor, much remains unknown about their biology and behavior.

“The joint survey is a fantastic opportunity to document the species that live in the Tasman Fracture Marine Park,” said Associate Professor Neville Barrett. “This rare sighting during a joint survey demonstrates the benefits of working in partnership with research institutions in managing our marine parks.”

Conclusion

The pink handfish serves as an intriguing example of marine biodiversity and conservation challenges. Continued research is essential to uncover more about this unique species and ensure its survival amidst changing environmental conditions.
