What does a marine biologist do​?

A marine biologist is a person who observes the sea and studies animals and plants that live in the ocean.
Let’s see what they do:

1. They Learn About Sea Animals and Plants

Marine biologists spend a lot of time learning about the animals & plants that live in the water.

They study:

• Fish (like tuna, clownfish, etc),
• Sharks (big fish with sharp teeth),
• Dolphins (smart & big animals that jump in the water),
• Whales (Whales are very big in size, and live in the sea),
• Jellyfish (soft animals that float),
• And even sea plants like seaweed (plants that grow underwater like water lily etc).

They want to know:

• What these animals eat (like small fish or plants),
• How do they live (do they live alone or in groups?),
• And how they grow (from child to adult).

They try to understand how sea animals stay healthy and safe in the ocean.

 2. They Work in the Ocean & Sea

Marine biologists don’t only work inside buildings.
They also go outside to the real ocean!

They may:

• Ride on boats &  to go far into the sea,
• Swim under the water using special clothes and masks,
• Take tools with them to collect things like water, sand, or small sea animals.

 3. They work in a lab 

After practical research or work, they come back to the lab for experiments to check these points.

In the lab, they:

• Check the sea water, is it clean or not,t from a sample of the water?
• Check (tiny creatures) plankton type of animal.
• With the help of microscopes (they observe very small things & animals and plants),
• Use computers to store information and do research.

 4. They Help Take Care of the Ocean

The ocean is in danger because of pollution (trash, plastic, and chemicals in the water), climate change, and too much fishing.

Marine biologists try to protect the ocean and the animals in it.

They may:

• Help sea animals that are sick, hurt, or stuck in fishing nets,
• Clean beaches or water areas with other helpers,
• Teach people to throw away trash properly,
• Ask the government to make rules that protect sea life (like no fishing in some areas).

 5. They Teach People About the Ocean

And then marine biologists teach all these techniques and research to the students in this way;

• Write simple books or articles for students or other scientists,
• Talk to kids in schools or make videos about sea life,
• Work in places like aquariums (big fish tanks where people can see sea animals),
• Help tourists or visitors learn fun facts about sea creatures.
