These calm marine mammals are some of our favorite things to encounter underwater. They're wonderful for underwater photographers because they congregate in some ares that can be enjoyed without the need for scuba equipment- meaning that you can bring your family and non-diving friends along too. Just remind them not to kick up the silty bottom.
Manatees are gentle and generally interested in you making it possible to get some very close encounters. Some will even start following you around like cute little half-ton puppies.
Florida Springs, and Crystal River although chance encounters happen in warmer tropical waters.

Get close and shoot up. Wait for close passes and shoot while the manatee is approaching. You are not allowed to swim over them, let alone chase them. Remember they will come up for air every 5 minutes or so, this is often when they will decide to come check you out with a face push.
Position your strobe(s) far away from the lens, just behind the focal plane and angled forward to reduce backscatter. These cannot be used until 1/2 hour after sunrise. In the crystal clear waters of the Florida Springs, we prefer natural light over flash.
