Habitat
Roundnose grenadiers inhabit deep waters of the Atlantic Ocean, primarily on continental slopes and rises at depths ranging from 180 to 2,500 meters. They prefer muddy or sandy substrates in cold, dark environments. These fish are found in both the Northwest and Northeast Atlantic, including areas around Greenland and the United Kingdom.
Diet
Roundnose grenadiers primarily feed on benthic organisms such as crustaceans, mollusks, and small fish like shrimp and lanternfish. They are opportunistic scavengers and predators, foraging along the ocean floor, often at night when they may be more active. Feeding behavior involves using their barbels to detect prey in low-light conditions.
Behavior
Roundnose grenadiers are generally solitary or found in small groups, exhibiting benthic lifestyles on the deep-sea floor. They are mostly inactive during the day and may become more active at night for feeding. These fish can undertake vertical migrations to follow prey or environmental changes, and they show little territorial behavior in their vast habitats.
Conservation Status
Listed as Critically Endangered by IUCN.
