Thalassia testudinum (Turtle grass) flower

Thalassia testudinum flower

Seagrasses are true flowering plants that live underwater. They live in shallow, clear water, allowing enough light for them to photosynthesize, just like land plants. They spread primarily through the growth of roots and rhizomes, often forming large meadows in sandy or muddy substrate. These root systems help stabilize sediment and reduce shoreline erosion.

Boat anchors and propellers cause great damage to seagrass beds.  Anchors can rip out the roots and gouge holes that undermine the surrounding root systems.  The area "implodes," and it may take years for these areas to recover, if they recover at all.

Never Anchor in Seagrass or Coral

The ornamental flamboyant tree is covered in bright orange-red blossom when in bloom.  

Did You Know?
When the flamboyant tree (Delonix regia) is in bloom, a crown of blood-orange flowers covers the tree. Long, feathery leaves and large seed pods are other distinctive features of this tree.
