Aquatic biologists are scientists who study organisms that live in water, including fish, amphibians, invertebrates, and plants. They explore various aquatic environments, such as oceans, rivers, lakes, and wetlands, to understand the complex relationships between these organisms and their habitats. Their research helps in assessing the health of aquatic ecosystems and the impact of human activities on them. These biologists often conduct field studies, collect samples, and analyze data to monitor species populations and biodiversity. They may also work on conservation efforts to protect endangered species and restore damaged habitats. Their findings contribute to environmental policies and sustainable management of water resources.
