What lives on the ocean floor?
These include animals such as sea cucumbers, sea stars, crustaceans and some worms. Other animals need to have something solid to attach themselves to the seafloor, such as sponges, hard and soft corals and some anemones.

Is the ocean floor flat?
Before scientists invented sonar, many people believed the ocean floor was a completely flat surface. … The smooth, flat regions that make up 40% of the ocean floor are the abyssal plain. Running through all the world’s oceans is a continuous mountain range, called the mid-ocean ridge(“submarine ridge” in Figure 14.23).
Is the sea level same everywhere?
Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, currents, river discharges, and variations in gravity and temperature prevent the sea surface from being truly level.
