Mangle rojo
The mangrove species that grows at the water's edge on those unmistakable arching prop roots. It forms the tunnels of the kayak channels and supports the dinoflagellates in the bioluminescent bays. Its fallen leaves feed that ecosystem, which is why bays with healthy mangrove glow brighter.
Example
When the guide says the bay glows because the mangrove is healthy, the red mangrove at the edge is what they mean.

Frequently asked questions
How do I recognize it?
By the arching prop roots that leave the trunk and enter the water. It is the mangrove right at the shoreline.
Can I touch or cut it?
No. They are protected by law and hold up both fisheries and coastal defense.
