They have evolved unique behaviors and morphological features in order to thrive in the cold and harsh Antarctic climate.

[9] Notothenia neglecta has gut flora composed almost exclusively of the bacteria Vibrio,[10] reflective of the ability of N. neglecta to tolerate high saline conditions and frequent ingestion of Antarctic krill,[11] which is composed of high amounts of chitin.

[14] N. neglecta possess an inflammatory response pathway that has made the fish suitable for the cold Antarctic environment.

[15] Additionally, N. neglecta synthesizes eight antifreeze proteins to combat the freezing temperatures of the environment.

[23] Benthic N. neglecta most commonly feed on krill, but in the summertime, heavily prey on salps.

[25] N. neglecta engage in unique behaviors that have allowed them to thrive in the harsh Antarctic climate.

[30] Scientists have observed fish become less reactive to availability of prey in the presence of another member of their species.
