Not just Shark
Pictures: Elasmodiver contains photos of sharks, skates, rays, and
chimaera's from around the world. Elasmodiver began as a simple web
based shark field guide 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
There are now
more than 5000 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 accessed here:

Behavior:Known to exhibit a threat display of head swinging and exaggerated
swimming. Often found in loose aggregations. Feeds on reef creatures such as
moray eels and other reef fish, cephalopods, and crustaceans. Larger individuals
may hunt smaller elasmobranchs and where available also prey on pinnipeds
Reaction to divers:An
extremely inquisitive shark. May persistently circle divers. Respect should be
shown around this animal especially larger individuals, however smaller
Galapagos sharks may be especially bold occasionally charging divers.
the Galapagos shark is known to occur around the world, it is commonly
encountered where it was first recorded at the Galapagos Islands of Ecuador. The
shark watchers Handbook lists Gordon Rocks off the North coast of Santa Cruz to
be especially good.
