Statement 1 is incorrect: They are found all over the world, including in Antarctica.

Statement 2 is correct: The Snailfish releases biofluorescence, which allows it to glow green and red in the dark arctic waters.

Statement 3 is correct: Snailfish found on an iceberg habitat in Greenland can survive in icy Arctic waters due to the presence of ‘antifreeze’ proteins in their bloodstream.
