Two of the tentacles are longer than the others. Squids have ten tentacles. However, there is only proof of some forty feet and smaller. Giant squids have the biggest eyes on earth. They range from eight to fifteen inches across.
Squids live throughout the world, except in arctic waters.
They eat small fish. Artists use squid's ink in drawing. It is called sepia ink. Squid is good to eat, at least I think so, anyway.
