Marine biology is the study of life that lives in the ocean! This means everything from tiny plankton to the biggest whales.
The ocean is really big and really deep, just like a giant swimming pool for all these creatures! Some of the animals that live in the ocean include fish, dolphins, whales, crabs, eels, jellyfish, and more.
Scientists who study marine biology watch these animals and try to figure out how they live, eat, and survive underwater. They also look at how the ocean works as a whole, what affects the animals in it, and how humans can take better care of it.
Learning about the ocean is important because the ocean helps make the air we breathe and helps control the temperature on land. It's important to keep the ocean clean and healthy so that all the animals that live in it can keep thriving.
