The Ocean is a very big place. The animals in the Ocean have many tactics to survive.
All animals in the ocean lay eggs. The interesting about this is that these animals try to go to the most perfect spots to lay eggs. Sometimes times most eggs die or a few die, it really depends on what species you are.
The Deep Ocean
The deep Ocean is very dark place, with a bunch of weird and creepy animals. Some of these animals almost go to the surface to lay their eggs. Other go to the surface at night time for food.
Turtles are a good example. They know it is time to lay eggs when you can only see half of the moon. When they see the moon they go to a specific beach and lay eggs there.
