Ocean Waves . . . :]

For Example: If we were studying Lunar tide changes. Different info can tell about gravitational pull. You can learn about ocean currents. You can warn ships and boats where there are treacherous waves.

Coasts . . . :]

The flatback turtles in Australia, find Crab Island every year to bury their eggs in the sand. They use there arms to push the sand over the eggs so they wont get destroyed while develpoing. After 6 or 8 weeks the turtles will hatch and its a race to the ocean to stay alive. The flat back turtles lay a lot of eggs at one as do other flat back turtles. All because the bby turtles have a better chance at surving so the birds dont kill them all.

Coral Seas . . . :]

Reefs harden into a limestone skeleton to form. Corals feed on plankton and sunlight. The Humphead Parrotfish eats the coral and turns it into sand.

The Deep . . . :]

There are these cool looking jellyfishes and squids that are transparent. They light up looking like a disco party. They have photophores which give them the ability to light up different colours. Some animals also use a light to detect food and confuse predators.
