It has eyes that are 10.6 in (27 cm) in diameter, meaning that even the eye of colossal squid fish is the largest eye in the animal kingdom. They die shortly after breeding and mating, but luckily, colossal squids are not extinct. Adult colossal squids may reach a total length of 46 ft (14 m) including their tentacles. Their weight increases with size and age, with adults thought to measure about 1000-1500 lb 456-680 kg). Colossal squids prey on chaetognaths, toothfish, and other deep-sea squids.
