Dolphins perform crucial roles in their native ecosystems. Tissue samples from a dolphin ecosystem can be used in studies regarding marine creatures, their prey, and chemicals or pollutants present in the bodies of water.

Admire them from a distance; never touch, feed, harm, or swim with a marine mammal. Whale health is linked to and is a critical indicator of ocean health. Although such changes in diet can have potential impacts on the health of the dolphins, parallel investigations on the trophic level these animals feed at (using isotope data from teeth) and the body condition of the dolphins (using long-term data on blubber thickness), indicated no adverse effects to the dolphins. This would disrupt the natural balance in the food chain and could negatively affect other wildlife and the health of the ocean environment. 2023 Ric O'Barry's Dolphin Project.

The application of the knowledge depends on what you value: for an academic, to further knowledge and understanding; for an applied researcher, to be able to provide information to managers on the implications of a range of management options, for a conservation biologist: to find ways of ensuring the health of populations and habitats. This project provides critical information on coastal dolphin communities, their lives and societies and shed light on how the health of these top predators, and the conditions of the natural resources they depend on, may directly or indirectly impact our own health and well-being.
