Description
The Onion-eye grenadier is a deep-sea fish characterized by its remarkably large, prominent eyes and a body that tapers to a long, whip-like tail. It inhabits the cold, abyssal waters of the North Atlantic and Arctic regions. As a predatory carnivore, it feeds on various benthic and pelagic organisms in its deep-sea environment.
