The world’s largest known fish breeding area has been discovered by a group of scientists in the coldest continent Antarctica. Researchers detect around 60 million nests of Antarctic icefish over a 240 square kilometers area in the Weddell Sea. These icefish are in a vast colony and it is called Neopagetopsis ionah.
The so-called icefish has some specialties- that it has a see-through skull and transplant blood. According to researchers, these icefish are the only fish group that has no red blood cells in their bodies. The fish have evolved an anti-freeze protein in their transparent blood to stop ice crystals from growing and thus, survive at such low temperatures, News18 reported.
The discovery has now been done by researchers and the revelation of the largest fish breeding in Antarctica has been done by Alfred Wegener Institute of the Helmholtz centre for Polar and Marine Research in Germany.
In February 2021, a team of researchers on the research ship Polarstone discovered a mind-boggling giant icefish breeding colony while surveying the beach with a camera system. The camera was used and dipped to a level of 535 underwater. Moreover, the study was published in the journal Current Biology after thoroughly evaluating their finding.
“We just saw fish nest after fish nest for the whole four hours, and during that time we covered maybe six kilometres (3.7 miles) of the sea floor,” Autun Purser, lead author and postdoctoral researcher at the Alfred Wegener Institute in Bremerhaven, Germany told media.
The researchers are now studying the other areas of Antarctica to know whether these types of fish colonies or any other type of breed occur or not.
