This is because there is a very special component in the blood of Antarctic cod. This component is called muscle sugar. To be precise, sugar is a chemical substance that can help cod resist cold. And it can effectively preserve blood in low temperature conditions created by us humans.humans.

Morphological characteristics

Antarctic cod is also called small-scale canine. Their body length is usually around 70 centimeters, and the maximum length can reach 2.15 meters.
