deep sea mysteries and oddities that will leave you baffled

Using hooks under its arms, the Gonatus onyx squid holds onto its huge egg mass for many months at a time before they hatch. Talk about a helicopter parent!

Looking like long lipstick containers, hydrothermal vent worms have neither a mouth nor digestive system. They thus rely on a relationship with bacteria which use chemicals to make food the worms can absorb.

Snails arent the first animal which come to mind when thinking about body armour, but a newly discovered (and so yet named) snail in the Indian Ocean uses iron compounds in the form of scales to protect its fleshy foot. The U.S. military is even researching the snail to improve its battle armour.

Looking a bit like a boat rudder, the bigfin squid was first seen off the Hawaiian coast in the mid 2000s and has been scarcely photographed. Including its tentacles, it can reach lengths of up to 16 feet (5m) long.

You might think nothing can live beneath the sea floor, but scientists recently discovered bacteria living 1,000 feet (300m) feet below it. Found by drilling through sediment and crust, the bacteria was feeding off residue many millions of years old.

The aviation industry has experienced numerous unexplained sea disappearances since its founding. Most recently with the Malaysian Airlines MH370 jet, one of the most famous pioneers, Amelia Earhart, also disappeared mysteriously. She and co pilot Fred Noonan disappeared over the Pacific Ocean in 1937. Millions of dollars have been funneled?into finding out the planes?whereabouts with no success. Rumours include running out of gas and being killed by Japanese troops for spying.

The year 1968 saw the still unexplained loss of submarines by four countries: the United States, Russia, Israel, and France. Some say the losses could have been government cover ups or (at least in the U.S. case) the nuclear tipped torpedoes misfiring into the vessel.

The bloop is another sound picked up by NOAA in the Pacific, but what makes it unique is it was detected at monitoring stations over 3,100 miles (5,000kms) apart. NOAA has now concluded it was ice breaking off a glacier, but some of its scientists still believe it could be a massive marine creature.

One of the more commonly referenced deep sea creatures, the anglerfish has an appendage coming out of its forehead with a light on the end. It uses this to lure prey in before devouring them with its over sized mouth.
