Do Squids Go Bloop?

Do Squid Go "Bloop"? Probably not. No one's ever heard a squid make any kind of noise, really, other than "splash" at the sea surface. But if you read io9's fantastic piece on the deep sea's mysterious sounds, you'll learn about The Bloop, an unexplained deep-sea noise from 1997.

Do squids go to the surface?

But because the ocean is vast and giant squid live deep underwater, they remain elusive and are rarely seen: most of what we know comes from dead carcasses that floated to the surface and were found by fishermen.

Do squids move?

Driven by the cephalopods' well known propulsion by pressing water from their pallial cavity, squids move backwards through the water like a rocket. Squids almost exclusively move that way. The jet's direction (and thus the direction of the movement) can be changed by altering the siphon's angle.
