There are two mosquito transmitted diseases (virus), Dengue, and Chikungunya Fever, now in the Caribbean. Both viruses are transmitted by Aedes species mosquitoes, which have black and white stripes markings. Please take a look at link information. More »

Seagrass beds are important and productive ecosystems in the shallow waters around St. John. Turtle grass, manatee grass, and shoal grass are true flowering plants, spreading primarily through growth of roots and rhizomes. These extensive root systems help to stabilize sediments which reduces shoreline erosion and helps keep the water clear.
Seagrass beds provide habitat for many fish species which find shelter in coral reefs during the day, and feed in seagrass beds at night. Turtles also graze in seagrass meadows as do Queen Conch (Strombas gigas) which feed on algae growing on the grass blades.
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

A wasp common to St. John is called the Jack Spaniard. These paper wasps are not aggressive, but will sting you repeatedly if disturbed. The sting can be quite painful, and should be treated with common sting relief remedies. The discomfort can last three days.
