The oceans of the world are still a mystery to marine biologists, and these images are guaranteed to amaze you
This is a species of porpoise found in the Sea of Cortez in Mexico. They are critically endangered as they are frequently entangled in fishing nets.
2. Black swallower
This fish has an elastic stomach pouch where it can store fish three times its size. They are deep sea fish that live up to 2,745 metres (9,000 feet) deep.
3. Ribbon seal
High in the Arctic lives this striped seal. The pattern helps the seals escape killer whale and polar bear attack, as it breaks up the animal’s outline.
4. Blanket octopus
Four of this octopus’ arms are connected by a sheet of skin and the others are extremely short. While females can grow longer than two metres (six feet), males only reach a few centimetres (One or two inches).
5. Headless chicken fish
Technically, it’s a sea cucumber rather than a fish. It has the ability to swim and can ascend 1,000 metres (3,280 feet) in the water column in search of plankton.
6. Hourglass dolphin
These must be the weirdest dolphins in the sea. They live off the east coast of Brazil and can’t stand warm water, preferring to head towards Antarctica when summer arrives.
You might not believe that this is a magnified image of regular sea water. It’s full of zooplankton – animals that are too tiny to propel themselves – which are so small that the water around them feels as thick as syrup.
