French Grunts

STATION #1: The school of fish in the foreground looking at you are French Grunts (Haemulon flavolineatum).  The name "Grunt" comes from the kind of sound these fish make.  Try and imagine you can hear them underwater!

You can see a kind of "soft coral" called a sea plume in the background, and the small, black-and-white-striped fish behind them are Sargeant Majors (Abudefduf saxatilis.)

Hope you enjoyed seeing all these French Grunts! Swim onto station #2.

Did You Know?

Gecko searching for insects.

One of the smallest lizards on St. John is the Dwarf Gecko. This tiny, inch-long reptile is native to the island, while many of the other geckos arrived on sailing ships in the 17th century. Dwarf Geckos feed on insects in the forest during the day, while most other geckos are nocturnal feeders.
