In case you readers weren't sure, this is a Giant Squid. Giant Squids have rarely ever been seen. Though they have eight tentacles, I have mistakenly drawn 10 tentacles on this squid. One of the most interesting and well known facts about Giant Squids is that their only predator is the Sperm Whale. In fourth grade I made a presentation and study on Sperm Whales for a class project. Unfortunately I have forgotten almost everything in fourth grade so I am unable to help you with facts about Sperm Whales. They are 20-45 feet long. Yes, that is a very long range. But all the same, these squids are gigantic.
