Have you ever heard of the giant squid? The giant squid lives in the abyssopelagic layer of the water column. Many invertebrate that live deep in the ocean are giant, or at least bigger than normal. Deep sea gigantism is where animals grow to an abnormally big size. Check out this photo of the largest crab in the world, Macrocheira kaemferi, from Japan being held by scientist Dante Fenolio.

Scientists are researching what causes deep sea gigantism. Some scientists think it is due to the high pressure exerted on the animals at these depths. Others think it is due to the scarcity of food. What do you think causes deep sea gigantism?
