The Dana octopus squid (Taningia danae) of the Pacific blinds its prey with flashes of light from its arms! It is believed that this highly maneuverable squid uses the bright flashes to disorientate potential prey. These flashes may also serve to illuminate the prey to make for easier capture as well as a courtship and territorial display.

A mind-blowing swarm of Velella velella - relatives of jellyfish - appeared off the coast of Washington state in the US last week, and researchers aren't entirely sure why.

The cookie cutter shark (Isistius brasiliensis) is as fearless as they come! This small, 20-inch shark can take on giants like whales and larger sharks, and have even been known to mistakenly try to bite submarines. They dwell in the deep warm ocean and come closer to the surface as the sun sets to grab a quick snack off their unsuspecting prey. Cookie cutter sharks approach their victims from below, latch on with their suction cup style lips, bite and then twist (below). A nice, round hole is left as a souvenir. They get this easy meal by tricking other ocean residents with their distinctive brown collar, which may act as a lure that allows the cookie cutter shark to be seen as a smaller, not-so-scary fish. As frightening as they seem, the ...

Lingcods are sometimes found with amazing, edible blue flesh. A bile pigment called biliverdin seems to be the cause, but exactly how it gets into the flesh of the fish remains a mystery.

No, Nintendo didn't make these. They're microscopic suckers found on squid arms, and they're each about 400 micrometres wide - smaller than the width of a human hair.

Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.

We know they kind of look and sound like a fancy dessert, but you won't find Little Egg Cowries on a dinner plate any time soon. In fact, you'll have a hard time finding them anywhere, because these spotty little sea creatures are masters of disguise. Through a process known as 'alimentary homochromy', they can change the colour, patterns, and shape of their flesh to perfectly mimic that of the coral and sea sponges around them.

Bearded fireworms are the caterpillars of the sea. At home in parts of the Atlantic Ocean and Mediterranean Sea, their bristles can pierce the skin of an unsuspecting swimmer and deliver a powerful venom that will burn for hours.
