Marine Biologists are scientists who work for laboratories and marine life centers to examine marine life and find ways to improve their ecosystem and environments. They’ll regularly take samples of sea creatures to see how well they adapt to different pollutants and others harmful exposures to their environments. Marine Biologists will analyze these samples to develop new theories and ways to help aquatic life have a safer and longlasting life in the ocean.

They’ll also discover new specimen by reviewing their samples. Many of them will also conduct experiments to track the ranges, movements and distributions of various marine populations. After conducting these experiments, Marine Biologists will create reports that detail potential harm that oil companies or other organizations could cause for the sea life.
