However, the biggest animal to ever live is the Great blue whale. They are bigger than the greatest known dinosaurs. Reaching 30 meters in length and weighting 180 tones, they have a heart the size of a car.

All life on land began 400 million years ago but life in the ocean began 3.1 to 3.4 million years ago.

Despite the oceans being home to some of the largest animals, the sea is also home to the largest living structure. The Great Barrier Reef measures 2,600 KM in the length and is so big that it can be seen from space.

The lowest point on earth is also in the ocean. The challenger deep, located in the Pacific Ocean has been recorded to reach depths of 10,920M or 35,827ft.

The highest tides in the world are at the Bay of Fundy. Sometimes, the difference between high tide and low tide is 16.3 M taller than a three story building.

The largest ocean is the Pacific Ocean aka. the peaceful sea.  This ocean covers 30% of the Earth’s surface.

The second largest is the Atlantic Ocean, which covers 21% of the earth’s surface. In the ocean you can find the Lion mane Jellyfish. This Jellyfish grows to 2.4 M or 8 ft.

Antarctica has as much ice as the Atlantic Ocean has water. Polar bears live on this ice. Unfortunately, the ice is shrinking 8% every 10 years.

You may think the sea is cold, especially in England but the top ten feet of the Ocean has as much heat as the Earth’s atmosphere. In addition, 99% of volcanic activity occurs in the Ocean.
