This grenadier, seen at 1,010 meters (3,313 feet) depth during the fifth dive of the second Voyage to the Ridge 2022 expedition, seemed a little skeptical about remotely operated vehicle Deep Discoverer. Grenadiers, also known as rattails, belong to the Family Macrouridae, which is the most diverse family within the order Gadiformes, with almost 400 recognized species. They have a worldwide distribution and are found at great depths, from the Arctic to the Antarctic. Members of this family are among the most abundant deep-sea fishes.
