Giant Squid • Not much is known about them other than they have the biggest eyeballs of all animals that are alive • They only live about 5 years and are fully grown by the 2nd or 3rd year • They live at extreme depths that no submarine could get to but sometimes surface to eat or mate
Giant Squid (continued) • They are about 15 m long and weigh about 1 ton • The scientific name for the Giant Squid is Teuditha and is an invertebrate • They can live anywhere in the water other than the Arctic and Antarctic • They have 8 tentacles, 2 feeding tentacles and beaks for mouths
Breeding • Their breeding grounds are in the Hokitika Canyon and Peninsula Banks • The male Giant Squid’s penis is found just below its beak in the form of a tentacle • The penis is about 1 m long which is about the size of its mantle (head) • The female Giant Squid’s sex gland is found in her tentacle also but her ovary is found in her mantle
Breeding (continued) • So to get the sperm from the arm to the mantle the female has 2 options to do this • Force the sperm up her arm and into the mantle to fertilize the eggs • Release the eggs and grab them with her arm that has the sperm in it • She releases about 3000 eggs but only a few actually survive
Breeding (continued) • Giant Squids can also reproduce male/male and female/female • When a male Giant Squid has sex it goes in with 8 tentacles, 2 feeding tentacles and 1 penis but after having sex it only has 5-6 tentacles, 2 or even possible 1 feeding tentacle and maybe even lose their penis
Cool Facts • Did you know that the Giant Squids eyeball is about the size of a blown up beach ball • Their massive organs let them sense anything even in the darkest of places
