The Giant Squid (genus: Architeuthis) is a creature once regarded as a hoax. In modern times, however, corpses that washed up on beaches proved its existence. It wasn't until 2004 that a Japanese saw and photographed a live one. Often it has been provided as explanation for cryptids like the Kraken.
The giant squid is purplish red, with eight arms and to tentacles. They typically range between 33 and 43 feet in length, but scientists state that their length could be exaggerated if the tentacles were stretched.
