Fish in Antarctica suffer from ugly skin tumors due to climate change

A new study has discovered a large number of Antarctic fish with hideous skin tumors.
Researchers at Ohio State University believe that the parasitic disease is spreading among fish as a result of climate change, and changing conditions include rising air temperatures and melting glaciers.
Scientists have noticed the appearance of hideous skin tumors in a unique group of fish called “notothenoids”.
According to the study published in the journal iScience, skin tumors in vivo were “pale, pink, raised and rough, and they appeared in various places on the trunk and head, and in some cases covered more than a third of the body’s surface.”

Commenting on the discovery, the chief scientist during the 2018 research expedition and lead author of the study, Thomas Desvins, said: “When life conditions become difficult, animals become more susceptible to disease.”
The authors of the study explained that “the waters of the Southern Ocean have been environmentally stable and chronically cold, hovering near the freezing point for the past 15-20 million years, however, the climate in Antarctica is changing rapidly, with rising air temperatures and melting glaciers, This contributes to warmer, clearer bottom waters.”
Scientists confirmed that they are currently preparing project proposals to go to Antarctica again in order to study this specific outbreak, how it has evolved since 2018, and to explore nearby areas, to try to see if they can detect the pathogen elsewhere and in other fish.
