Behavior and health

Understanding how marine mammals live, thrive, and adapt

Protecting aquatic mammals starts with understanding how they live in the wild. Their behavior and health reveal how life beneath the surface adapts to a changing planet.

At NMMF, our scientists study health, behavior, and population dynamics to understand how aquatic mammals respond to environmental pressures. By pairing long-term observation with advanced tools like ultrasound and genetic analysis, we can see the story of a population unfold before it reaches a tipping point.

Every insight we gain helps shape conservation that protects both individual animals and the ecosystems they depend on.

Why Behavior and Health Matter

Behavior as an Early Indicator

Aquatic mammals are early messengers of ecosystem change. When prey becomes scarce, noise intensifies, or a habitat begins to degrade, the first signs appear in the way they feed, travel, and communicate.

By documenting these behavioral changes over time, NMMF scientists can identify stress at its earliest stage, while a population still has the capacity to recover. Acting early gives conservation interventions the greatest chance to succeed.

Behavior change is often the first warning sign, long before illness appears.

What These Discoveries Tell Us About Aquatic Life

From Knowledge to Action

What we learn from health and behavior becomes the foundation of stronger, earlier protection –  before a species crosses the tipping point. By listening to what these animals are telling us now, we have the chance to act while recovery is still possible.
