Fish “Chock-Full” of Antifreeze Proteins Found in Iceberg Habitats off Greenland; Snailfish Study Reveals Highest Expression Levels of Antifreeze Proteins Ever Reported

New research based on an expedition to the icy waters off Greenland reveals soaring levels of antifreeze proteins in a species of tiny snailfish, underlying the importance of this unique adaptation to life in sub-zero temperatures. The study, led by scientists at the American Museum of Natural History and the City University of New York (CUNY), and published om August 16, 2022 in Evolutionary Bioinformatics, also warns that warming oceanic temperatures in the Arctic could pose a threat to these highly specialized fishes. The article is titled “Transcriptomics of a Greenlandic Snailfish Reveals Exceptionally High Expression of Antifreeze Protein Transcripts.”
