Fish: Fish are the most common sea life on Earth. They have bones just like humans, but they are covered with scales, have fins, and breathe through gills. The most common type of fish is the bony fish. They are called as bony fish because their teeth are made out of bones. Tuna and goldfish are types of bony fish.
Sharks: Sharks are types of fish too. There are many kinds of shark like the great white sharks which is the fiercest predator in the ocean and the whale shark which is really large. Sharks have to keep swimming to not go to the depths of the ocean.
Creatures that Sting: There are many creatures in the ocean that sting to get food and escape water. There are the coral polyps that use their tentacles to sting their predators and they also use their tentacles to catch food. Jellyfish also use their tentacles to sting their prey and catch food, they are so transparent.
Marine Mammals: Marine Mammals mostly live in land and water. The most common mammals are seals, sea lions, dolphins and whales. Seals and sea lions spend more time on land than water cause they have lungs to breathe. Whales and dolphins have blowholes and spend more time in water. They come up to the surface to breathe and one deep breathe can make them stay in the water for up to 2 hours. All marine mammals give birth to young alive and feed the young with milk.
Seabirds: Most seabirds live on land and search for food in the water. Most seabirds search for food by the shore and nest on land. But some seabirds like the Albatross have long weeks so they can fly for 1 week without stopping to rest so they go deeper above the ocean to search for food.
Squid and Octopuses: Squids and octopuses both have streamlined bodies. They live in the bottoms of the ocean and hide near rocks or caves and camouflage so they can catch their prey. Whenever a predator attacks them they move quickly or they squirt ink so that the predator will get confused and go away.
Sea Stars: Sea Stars are really dangerous and poisonous even though they are slow. Many sea stars have only five legs but some have 8 or more legs. Under the legs are suck cups which suck blood from any predator or prey and their mouths are placed on their underside.
Crustaceans: Crustaceans are sea animals with no backbones (invertebrates). They live on the ocean floors too. Crabs and shrimp are crustaceans. The most common type of crustacean is the krill. Even the world’s largest animal the blue whale feeds mainly on crustaceans.
