A rare bottlenose dolphin missing its tail flukes has been spotted living in Charleston-area waters, according to the Lowcountry Marine Mammal Network.
Dolphin Named “Koa”
The dolphin, named Koa, was first reported to researchers in March 2025.
Officials said Koa is missing its tail flukes, which are essential for swimming and movement. Experts say it is extremely rare for a wild dolphin to survive long-term with this type of injury.
The name Koa means “Little Warrior” in Hawaiian.
Experts Call Survival Remarkable
According to LMMN Executive Director Lauren Rust, a dolphin’s tail normally acts as its main source of power in the water.
Researchers said Koa has continued to survive, travel, and forage despite the disability.
LMMN noted that only six similar cases involving wild dolphins have been documented worldwide.
Public Asked to Give Dolphin Space
Researchers said Koa has been seen in busy waterways around Charleston and may be more vulnerable to stress caused by boats and human interaction.
LMMN is asking the public to:
- Keep a safe distance from Koa
- Avoid touching, feeding, or chasing the dolphin
- Not swim with the animal
- Avoid crossing its path in the water
- Travel slowly in areas where wildlife may be present
Sightings Can Be Reported
The organization encourages anyone who spots Koa or notices concerning behavior to contact the Marine Mammal Stranding Response Hotline at 800-922-5431.
Researchers say they will continue monitoring Koa and plan to provide updates in the coming weeks.
