The legato handfish ( Sympterichthys unipennis ) is formally no more , declare out by the International Union for the Conservation of Nature ( IUCN ) . Although extinctions are now tragically common , this one is notable because it is the first marine fish species to be consider a “ modern extinction ” , that is with specimen collected in historical time rather than only being known from fossils . The declaration deals a blow to the theory the ocean is so Brobdingnagian marine Pisces will always receive a raw house . Worse still , several other handfish coinage are probably already gone .
Handfish survive on the seafloor off the coast of Tasmania . They are like nothing else on Earth , having largely foregone swim to pull themselves along the sea bed using flippers that wait like hands . TheHandfish preservation Projectsums them up with an anonymous citation : “ If you ’ve never seen a handfish before , imagine douse a toad in some brightly coloured pigment , telling it a sad story and draw it to outwear gloves two size too big . ” Museum specimens could easy be mistaken for toss props from aStar Warsfilm .
Although they were in all probability never abundant , handfish were certainly divers , with 14 species engross unlike ecosystem when Europeans arrived in Australia . unhappily , however , most have not been seen in this hundred . The smooth handfish is known only from a specimen pull together by Gallic explorers in the early 1800s .
After two centuries without being see , the ICUN has decide this one is almost certainly lead , changingits statusto extinct .
Dr Jemina Stuart - Smithof the University of Tasmania is an expert on handfish . She told IFLScience that , even though we have it off of no surviving universe of most other handfish specie , marine biologists still hold onto Bob Hope , in particular for those that choose deeper waters where divers seldom go .
The three species that do still exist are all rare , however , with two of them the direction of desperate conservation efforts . The crimson handfish is down to fewer than 100 adults , each of which has a personal webpage . To raise money to protect them , people and companies are paying tochoose the nameof an individual Pisces .
Handfish , in general , are threatened by increased sediments washed out of Tasmania ’s damaged watershed . Climate variety is almost certainly also a factor , and a scallop piscary that shut down more than 50 years ago probably do a sharp diminution that pushed many species close to the edge .
Some handfish face specific threats . Stuart - Smith told IFLScience nail native sea urchin are eating the seaweed that help protect the reddish handfish in their bouldered habitats . Meanwhile , pick out handfish prefer flaxen bottoms where the stalk ascidian they cast anchor their eggs to are being eaten by encroaching sea stars .
The conservation project is appealing for divers to look out for the handfish of the live species and account any sightings . “ We ’re roll up cherry-red handfish egg from the wilderness to concoct in imprisonment where we can protect them from threat before secrete them , ” Stuart - Smith told IFLScience .
The handfishes stage a warning about how extinction can creep up on us if an animal is not particularly expectant or famous . Handfish research was so under - resourced that until recently no one earn how expose most of the species were .
