The sea has coughed up an oddity. It has eyes a foot in diameter, the largest of any animal. It has eight arms and two huge long tentacles with razor-sharp hooks on the end, which it uses to rip its prey to shreds. It doesn't have teeth, it has beak-like hooks. In order to find food, it glows, lighting up the deep dark waters where it swims. It's meters longer than the largest whales.
Fishermen near Antarctica discovered this, a massive beast, but it's just a baby. They believe there are even more massive squids out there. Be afraid...
They couldn't call it a "giant squid" because that name is already used, so it's (temporarily?) the "colossal squid".
Scientists kinda knew *something* was out there before finding this one, because of squid meat found in the stomachs of whales. Interesting!
And they think there must, now, be other beasts in the deep ocean that we just don't know about.
