The Boreoatlantic armhook squid (Gonatus fabricii) is named for its fabulous (but dangerous) suckers. While most squids have just two rows of suckers lining each arm, armhook squids have four—and the middle two rows have small, sharp hooks protruding from the center. These hooks are used to capture prey and as a defense. See more at the NOAA Ocean Explorer mission log, and see other animals from Under Arctic Ice.
