Marine animals are animals that live in the ocean. There is a very big variety of animals in the ocean. They hunt, camouflage, and can be bioluminescent.
Hunting is essential to any animal’s life. Orcas are apex predators, meaning they don't have their own predators. Some other apex animals are sharks and seals. Orcas and sharks will sometimes hunt each other. Some fish hunt in large groups, from the hundreds to the thousands. Animals use some hunting tactics to help get their meal. For example, Orcas can cause tonic immobility, meaning that whales crash down on their prey’s head and flip them over. Animals may use some form of communication to help while hunting.
Camouflage is another tactic used to hunt or hide from predators. Animals can camouflage themselves on the seabed, in the crevices of rocks and in coral reefs. Animals may use camouflage to hide from predators. Some animals, such as octopuses and many other fish, are masters of camouflage.
Bioluminescence is when a living organism glows in the dark. Bioluminescent light is produced by symbiotic bacteria within light-emitting cells and is called photophores. Bioluminescent animals usually lurk in the deeper part of the sea. Lots of different types of jellyfish are bioluminescent. So are many different types of fish.
