"Scientists drilling deep into an iceberg off Greenland have discovered a fish with glowing green antifreeze coursing through its veins.

"The juvenile variegated snailfish (Liparis gibbus) contained the "highest expression levels" of antifreeze proteins ever reported, a new study found.

"Similar to how antifreeze helps to regulate the temperature of a car's engine in extreme conditions, certain species have evolved to have similar protection, especially those living in frigid habitats such as the polar waters off Greenland.

"'The fact that these different antifreeze proteins have evolved independently in a number of different — and not closely related — fish lineages show[s] how critical they are to the survival of these organisms in these extreme habitats," John Sparks, a curator in the AMNH's Department of Ichthyology and co-author of the study, told Live Science in an email.

"Snailfish produce antifreeze proteins "like any other protein and then excrete them into their bloodstream," Gruber said. However, snailfish appear to be "making antifreeze proteins in the top 1% of all other fish genes."

"This mind-boggling level of antifreeze production could help this species adapt to a subzero environment, according to the statement."

Comment: how does natural selection find these necessary complex protein molecules? Not likely. I can 't just grab them off a shelf. Design is a better fit.
