Entitled: "A.E. Verill from nature." The giant squid (genus Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae. Giant squid can grow to a tremendous size due to deep-sea gigantism: recent estimates put the maximum size at 43 feet for females and 33 feet for males from the posterior fins to the tip of the two long tentacles. The mantle is about 6.6 feet long (more for females, less for males), and the length of the squid excluding its tentacles (but including head and arms) rarely exceeds 16 feet. Claims of specimens measuring 66 feet or more have not been scientifically documented. Addison Emery Verill (February 9, 1839 - December 10, 1926) was an American zoologist. From 1860 Verrill investigated the invertebrate fauna of the Atlantic coast, with special reference to the corals, annelids, echinoderms, and mollusks, and became the chief authority on the living cephalopods, especially the colossal squids of the North Atlantic.
