Mosquito Lagoon dolphins are not just visitors passing through.
NOAA recognizes the Indian River Lagoon Estuarine System as home to a distinct stock of bottlenose dolphins, with long-term site fidelity to the lagoon. Researchers can identify individuals by the unique nicks, scars, and markings on their dorsal fins, which means some of the dolphins we see here are known, recognizable residents of this ecosystem.
These dolphins are top predators, social animals, and sentinels for lagoon health. When seagrass declines, prey changes, water quality suffers, or fishing gear ends up in the water, dolphins feel those changes too.
That is why dolphin conservation in Mosquito Lagoon starts with protecting the lagoon itself. Clean water, healthy seagrass, strong fish populations, and respectful wildlife viewing all matter.
Watch quietly. Keep your distance. Never feed wild dolphins. Let them hunt, travel, rest, and raise their calves naturally.
The best dolphin encounter is one where they stay wild.
