The long-fingered icefish is a fish that lives in very cold waters around Antarctica. It has no hemoglobin in its blood, so the blood is transparent, and the meat looks pale.
The long-fingered icefish differs from other fish by its transparent blood without hemoglobin and special antifreeze substances. It plays an important role in the Antarctic food chain as a predator and prey for seals and birds.
Immature form that undergoes metamorphosis before adulthood.
