Marine Biology

Scientists have speculated about the cognitive and dreaming abilities of the octopus. This study is a step closer in understanding their complex behavior. As does a study on cuttlefish from the same team, showing their color shifting like never before.
-
Scientists have used fossilized megalodon teeth to estimate the ancient shark’s body temperature, and found it wasn’t exactly a cold-blooded killer. Strangely enough, that might have contributed to its downfall.
-
With evolution there’s always a trade-off – long necks may help you find food but they’re also a massive weak spot. Now, paleontologists have found direct fossil evidence of prehistoric, long-necked marine reptiles being decapitated by predators.

Paleontologists have discovered fossils from a gigantic marine predator that stalked the Jurassic seas. The creature could have grown to twice the size of an orca, and fed on pretty much anything else unlucky enough to be in the ocean at that time.
-
In a surprising first, researchers found that scalloped hammerhead sharks act like air-breathing marine mammals, holding their breath to stay warm when they deep-dive into cold water for food and making them vulnerable to humanity's deep-sea exploits.

In 1986 it got up close to the Titanic, and now deep-sea explorer Alvin is achieving more world firsts, this time documenting 1.2 miles of new reef featuring live coral that's thousands of years old. Scientists hope it's the first of many to be found.
-
Scientists have discovered that the feces of coral-biting fish is brimming with beneficial symbionts. If scientists could get stressed-out coral to take them on board, essentially a 'poop transplant,' it may help reverse some forms of coral bleaching.
-
ESA's Sentinel-2 satellite is tracking what may be the largest bloom of Sargassum seaweed ever recorded as it drifts toward the US East Coast, threatening to dump millions of tons of rotting vegetation on thousands of miles of beaches.
-
With their little flipper-like wings, these seabirds aren’t exactly candidates for being adept at pumping iron. But, in fact, they are: more than a million pounds of iron flows from their poop into the water annually, and it's crucial for ocean life.
-
After nearly 20 years of negotiations, 193 nations have come together to draft the High Seas Treaty, an agreement that will set the world on track to protect 30% of international waters, fund marine conservation and better regulate sea-bed mining.
-
Scientists from King Abdullah University of Science and Technology studying tiger sharks have leveraged their far-roaming tendencies to map out the largest seagrass system in the world, by using cameras attached to their backs.
-
Scientists studying the behavior of wild octopuses off the coast of Australia have made a strange discovery, with the creatures caught hurling silt, algae and even shells at one another in a rare example of animal throwing behavior.
