Giant Rattail Fish (Albatrossia pectoralis)
This large rattail is found at depths between 140 and 3,500 meters, and it has been known to reach lengths of up to 2.1 meters. The oldest reported A. pectoralis was 56 years of age. Many traits of the Rattail belong to the Giant Rattail (or Giant Grenadier), as well, such as the elongated snout and distinctly pointed tail. The Giant Rattail consumes mostly squid, but other echinoderms and amphipods as well.
