Corals and mangroves share clear waters
Sediment can smother corals, but Hurricane Hole has no sediment-bearing freshwater streams. Its clear waters are habitat for an entire community of marine life, including Montastrea corals and squirrelfish. Photo: Caroline Rogers, USGS, 2009

Red Mangrove trees
The seedlings of Red Mangrove trees germinate from fruits while still attached to the trees. Here many are growing within the roots of adult trees.

Flat Tree Oyster (Isognomon alatus)
At high tide, the red bark of the Red Mangrove Trees is submerged, creating a brilliant reflection at the water's surface. Flat Tree Oysters (Isognomon alatus) grow on the upper portions of the roots.

Sponges in the Hurricane Hole mangroves
Sponges, such as the blue, green and orange ones growing on these prop roots, provide much of the color in the Hurricane Hole mangroves.
