MONSTERS OF THE DEEP
… are sea-dwelling mythical or legendary creatures, often believed to be of immense size.
Marine monsters can take many forms, including sea dragons, sea serpents, or multi-armed beasts. They can be slimy or scaly and are often pictured threatening ships or spouting jets of water. The definition of a “monster” is subjective, and some sea monsters may have been exaggerations of scientifically accepted creatures such as whales and types of giant and colossal squid.
Nevertheless, stories of sea monsters and eyewitness accounts which claim to have seen these beasts persist to this day.
Such sightings are often cataloged and studied by folklorists and cryptozoologists.
