The Giant Squid is a very large cephalopod that belongs to the squid family. Although it is confirmed to exist now, it was a cryptid for a long time.
A large mantle, a beak, eight flailing arms, and two long tentacles, lined with sharp-serrated suckers are hallmarks of a squid. Giant squid, however, are said to be much larger. Rather than a 6 ft. cephalopod, giant squid are said to reach sizes upwards of 100 ft., larger than an average fishing trawler.
