In a mask or glasses with thick glasses, you can sink to the bottom of the sea and see a lot of unusual things in the sand and among the rocks! Around are many colorful fish and shellfish. Others jump like grasshoppers, while others chase prey or run away from enemies. Sand stretches all the way down and hides in the dark, where the sea goes deeper. At the bottom of the seas there are mountains. And in the oceans there are whole mountain ranges with a height of more than 10 thousand meters.

Underwater meadows

In shallow water under warm sunshine, algae grow well, and therefore the bottom looks like a meadow. Here herbivores graze

Sea shores are not always gentle, with beaches or grass. There are also bare rocks extending to a greater depth - fish and many different mollusks. In other places, the seabed is covered with corals, unusually diverse in shape and color. However, they are hard and sharp.

Interesting fact: to explore the seabed, a diver puts on a spacesuit. However, at great depths, the water pressure is so great that the human body does not withstand. Therefore, scientists go down there in the bathyscaphe - a large metal ball with thick glass windows, into which you can look at the underwater world. If several people need to sink to the bottom, they use a submarine.
