Giant Squid: Giant squid can grow to a extraordinary size due to deep-sea gigantism, which is the tendency of invertebrates and other deep dwelling species to be larger than their shallow water counterparts. Estimates put the maximum size of a giant squid at 43 ft (13 m) for females and 33 ft (10 m) for males from the posterior fins to the tip of the two long tentacles. The mantle is approximately 6 to 7 ft (2 m) long, and the length of the squid excluding its tentacles, while including head and arms, rarely exceeds 16 ft (5 m). Giant squid have eyes measuring a foot (30 cm) in diameter, which is the largest in the animal kingdom. These large eyes help absorb more light to locate bio-luminescent prey and spot predators at a distance.
