Watch rare endangered pink handfish walking in 19th-century shipwreck off Tasmania

Scuba divers exploring a shipwreck off the coast of Tasmania got a huge surprise when they spotted an extremely rare pink handfish, and managed to capture the elusive creature on video. 

The handfish (Brachiopsilus dianthus) was hidden among the coral-covered debris, with its hand-like pectoral fins extended. There have been only a handful of encounters with the pink handfish since the species was discovered in 1947.

Divers noticed the fish during an exploratory dive to the Dutch steamship, SS Tasman. "We were there to explore the wreck, but the handfish stole the show," Brad Turner, a member of the dive team who found the fish, said in a statement emailed to Live Science. 

The remains of the SS Tasman — a steamship built in 1873 and used to transport cargo and passengers — are located near the granite island of Hippolyte Rocks 6.2 miles (10 kilometers) from the mainland of Tasmania. During an attempt to go through a narrow passageway, the ship sank when it struck an uncharted reef. The 29 passengers and crew members escaped, but left 75 cows aboard.

This dive was part of a series of explorations planned to commemorate the 140th year anniversary of the sunken ship.  

At 230 feet (70 meters) below the surface, divers had 25 minutes to explore, staying mindful of their oxygen levels for a 90 minute ascent back to the surface. As the dive came to an end they had another shock when they spotted a second pink handfish, just 32 feet (10 m) from the first, Turner in the statement.

B. dianthus is one of four endangered handfish species found in Tasmania. Unlike other fish, handfish do not have swim bladders to control their buoyancy underwater, so they stay close to the rocky seabeds and can only swim short distances.
