Say cheese! Most people would swim a mile if they saw this great white shark coming, but a group of top photographers have got up close to show what life is like under the sea.
This snap of a grey seal was taken off the coast of the UK, showing us that there is hidden underwater life right under our noses!
These manta rays were spotted in the Maldives. They love to eat plankton and when there's loads in the area hundreds of rays go to chow down!
It's a nice life for a manatee! These creatures, sometimes known as sea cows, usually spend up to half of everyday sleeping.
Marbled rays like these love to swim in warm oceans. They have massive plate like teeth which they use to squash their favourite snack - worms!
This bright yellow guy is called a lemon shark. Unlike most other types of shark they live well in captivity which is really useful for experts trying to study them.
Every year 70 million sharks like this great white are killed for their meat and fins. The photographers are hoping that their snaps will help to raise awareness of the problem.
Scientists worry that if sharks continue to be killed at the current rate then 12 species, including this basking shark, could be extinct by 2017.
