Why don't fish freeze?

Hi,

How can fish not freeze solid in Antarctic water? Can't we use it?

Love the podcasts & hope you had a great vacation.

We do use it!

Antarctic and Arctic fish don't freeze at the very low water temperatures found there because their genomes posses a gene that is expressed as glycoprotein, an anti-freeze protein, in their blood plasma. This depresses the freezing point of their blood in the same way that ethylene glycol works in an engine block.

And also genetically engineered tomatoes that are frost-resistant!
