I have always believed that there are gargantuan sea monsters alive in the volumous ocean depths.
From ancient times sailors have told and retold stories of sighting the huge many-tentacled beast called the Kraken. We now know that a creature very similar to Kraken descriptions exists, the Colossal Squid. In 2007 the largest known Colossal Squid was captured in the waters off New Zealand. It weighed 495kg and was 10m long. How big does the Colossal Squid grow? No one knows. Is there larger undiscovered Kraken-like creatures alive today? No one knows.
