Elasmodiver.com contains images of sharks, skates, rays, and a few
chimaera's from around the world. Elasmodiver began as a simple web
to help divers find the best places to encounter the different
species of sharks and rays that live in shallow water but it has
slowly evolved into a much larger project containing information on
all aspects of shark diving and shark photography.
now more than 10,000 shark pictures and sections on shark
evolution, biology, and conservation. There is a large library of
reviewed shark books, a constantly updated shark taxonomy page, a
monster list of shark links, and deeper in the site there are
numerous articles and stories about shark encounters. Elasmodiver is
now so difficult to check for updates, that new information and
pictures are listed on an Elasmodiver Updates Page that can be

Nocturnal. Lays motionless during the day resting on pectoral
fins, partially covered by sand. Forage at night for worms in substrate.
Occasionally eat small snake eels. When threatened this ray can perform an
explosive outside loop, displaying its lighter underbelly and shocking the
predator. This is followed by a swift retreat.
Whilst following this ray, I observed it perform an evasive
maneuver in which it rapidly kicked up sand in a plume which suggested it had
shot forward and swum away. In the same instant it span around and came to
rest completely covered in sand directly under my body. It made no attempt to

Reaction to divers:
Easy to approach with slow movements. Can shock
(about 37 volts max.) if molested but usually swims away.
This ray is easily found when traveling over sandy areas
in its range. In Carriacou it was particularly abundant when diving from shore
in 10 to 15ft of water. Tanki's watersports located on the beach can rent
equipment for a shore dive which should also turn up some gold spotted eels,
flying gurnards, and the odd spotted snake eel.
