Now that we know about all four of the
oceans, let’s examine…
The saltiest water is in the Red Sea and the least salty water is in the polar region the melting ice caps and a lot of rain contribute to diluting the water.
The Dead Sea is so salty you can float in it!
There are literally millions of animal species in the ocean. To name a few, there are crustaceans, whales, seals, sharks, lobsters, crabs, plankton, jellyfish, and every type of fish you could ever imagine! Let’s learn more about these animals!
Lobsters are a type of crustaceans, they have a tough shell or exoskeleton and live on the ocean floor. They are mainly nocturnal, meaning they come out at night, and are predators of crabs, clams, worms, and snails. Lobsters can live to be 100 years old!!
Blue whales are the biggest animals in the ocean and on earth! They breathe through two blow holes that can push water up 40-50 feet above the surface of the water. They live in small groups called pods and eat tiny crustaceans, plankton and small fish
The octopus is an eight armed animal that lives on the ocean floor with each arm having two rows of suction cups. It also has an eye on each side of its head so the octopus has very good eyesight. It moves by walking on its tentacles and lives in dens, spaces under rock, crevices in the sea floor. In order to escape from predators, octopus’ squirt black ink into the water which allows them to escape.
Sea anemone look like plants but are actually predatory animals. They live attached to firm objects in the seas, usually the sea floor, rock, or coral, but they can slide around very slowly. There are over 1000 species of anemones found in coastal waters worldwide, in shallow waters and in deep oceans. They come in many different shapes and sizes, and eat fish, muscles, and worms.
Average dolphins grow to be about 12 feet long, sometimes weighing more than 1,400 pounds. They eat mostly fish and squid with their many pairs of sharp pointed teeth. Sharks and orca prey upon dolphins, they also often get trapped in people’s fishing nets.
Seahorses are a type of small fish that have armored plates all over their body (they don't have scales). There are about 50 different species of seahorses around the world. They live in seaweed beds in warm water and are very slow swimmers. Seahorses can change their color to camouflage (hide) themselves in order to hide from enemies. They swim by moving the fin on their back.
Just a few of the millions of fish that live in the ocean!

Certain species of these animals that make their homes in the ocean, grow fewer and fewer each day when they are over hunted or oceans are polluted.
