description Roundnose Grenadier Overview
The roundnose grenadier, Coryphaenoides rupestris, is a deep-water rattail fish of the North Atlantic. It has a large head, a body tapering into a long tail, and inhabits continental slopes and deep oceanic waters, where it feeds on fishes and invertebrates. Its slow growth, late maturity, and low reproductive rate make its populations vulnerable to fishing pressure, and intensive deep-sea trawling caused major declines in parts of its range.
