Scuba divers exploring a shipwreck off the coast of Tasmania come a immense surprisal when they spotted an passing rare pinkish handfish , and managed to beguile the problematic creature on video .
The handfish ( Brachiopsilusdianthus ) was hidden among the red coral - covered debris , with its deal - like thoracic fins lead . There have been only a handful of skirmish with the pinkish handfish since thespecies was discovered in 1947 .

diver noticed the fish during an explorative diving to the Dutch steamship , SS Tasman . " We were there to explore the shipwreck , but the handfish stole the show , " Brad Turner , a member of the dive team who found the Pisces , said in a statement netmail to Live Science .
Theremains of the SS Tasman — a steamer built in 1873 and used to transport shipment and rider — are located near the granite island of Hippolyte Rocks 6.2 geographical mile ( 10 km ) from the mainland of Tasmania . During an attempt to go through a narrow passage , theship sank when it strike an uncharted Rand . The 29 rider and bunch members escaped , but go away 75 Bos taurus aboard .
This dive was part of a series of explorations planned to commemorate the 140th year anniversary of the deep-set ship .

At 230 feet ( 70 meters ) below the surface , plunger had 25 minutes to explore , detain aware of their O level for a 90 minute ascent back to the open . As the dive came to an destruction they had another impact when they recognise a 2nd pinkish handfish , just 32 metrical foot ( 10 m ) from the first , Turner in the statement .
B. dianthusis one of four endangered handfish species found in Tasmania . Unlike other fish , handfish do nothave swim bladdersto check their buoyancy underwater , so they stay near to the bouldery Davy Jones’s locker and can only drown brusque distances .
" A key adaptation to their environment is their disguise ( they front like sponges on the seabed),“Neville Barrett , associate professor of ecology and biodiversity at the University of Tasmania , tell Live Science in an email .

They use this disguise to avoid detection by target and predators , and apply their outstandingly shaped fivesome to help them run . " Their thoracic fins haveevolvedinto deal - comparable structures that rent them baby-sit on the ocean bottom and quickly pounce on occur target , " Barrett pronounce .
Scientists previously believe pink handfish live in shallow waters to a maximum depth of 125 metrical unit ( 38 m ) .

In 2021 , the Institute of Marine and Antarctic Studies and the University of Tasmania used bait distant underwater video and autonomous subaquatic vehicles to record its occurrence at a depth of around 394 infantry ( 120 m ) for the first time . This was also thefirst time the pink handfish had been see in the 20 years since its discovery .
" The sighting is part of several recent uncovering in the preceding two years that have shown us that this species can endure a lot deeper than previously thought , " Barrett said . researcher suggest that pinkish handfish have been step by step move from warm shallow water supply to the refuge of cooler , deeper water supply , raising concern about whether the coinage will make it .
" This home ground will be gravely threatened by spherical thawing and the species could easy be nonextant in the next 100 years , " Barrett warned .
