E. dofleini move through the open water using jet propulsion, which is achieved by drawing water into its body cavity and then forcefully expelling it through a siphon, creating a powerful thrust and propelling the octopus through the water at a high speed. [25] [26] When moving on the seafloor, however, the octopus crawls using its arms.
The Caribbean reef octopus lives in warm waters around coral reef environments and grassy and rocky sea beds. Their biogeographic regions are as follows: the Nearctic region, Neotropical region (Central and South America), oceanic islands and the Pacific Ocean. The Caribbean reef octopus lives in hidden, rocky lairs that are difficult to locate.
Dumbo octopus: this octopus usually lives at a depth between 1,000 and 7,000 meters, deeper than any other known octopus. They use the fins on top of their head, which look like flapping ears, to hover over the sea floor looking for food. They use their arms to help change directions or crawl along the seafloor.

Sharks are found in all seas. They generally do not live in fresh water, with a few exceptions such as the bull shark and the river shark which can swim both in seawater and freshwater. [101] Sharks are common down to depths of 2,000 metres (7,000 ft), and some live even deeper, but they are almost entirely absent below 3,000 metres (10,000 ft).
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
"Sharks inhabit pretty much every ocean, every sea, every marine environment on the globe, so if you're speaking to kids, it's about them paying attention to what's happening in and around the ...
Hammerhead sharks eat a large range of prey such as fish (including other sharks), squid, octopus, and crustaceans. Stingrays are a particular favorite, with the positioning of their (comparatively) smaller, crescent-shaped mouths underneath their T-shaped heads allowing for skilled skate, ray, and flounder hunting, among other seafloor-dwellers.
