What is an Icefish?

Answer 1

Icefish, belonging to the family Channichthyidae, are a unique group of fish found primarily in the Southern Ocean around Antarctica. They are notable for their transparent bodies and lack of hemoglobin in their blood, which gives them a pale appearance and allows them to thrive in cold, oxygen-rich waters. Instead of hemoglobin, icefish use a different protein to transport oxygen, and they have adapted to survive in extreme environments where other species might not. These fascinating fish play a vital role in the Antarctic ecosystem.
