Protecting Marine Life

Healthy marine species like whales, sea turtles, coral, and salmon are important for maintaining balanced and thriving ocean ecosystems. We work to protect marine species populations from decline and extinction, conduct research to understand their health and environment, and evaluate and monitor human activities that might affect them to ensure future generations may enjoy them.

Marine Mammal Protection Act

The MMPA makes it our job to protect all whales, dolphins, porpoises, seals, and sea lions. This law prohibits, with certain exceptions, the "take" of marine mammals—including harassment, hunting, capture, collection, or killing—in U.S. waters and by U.S. citizens on the high seas.
