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:

There are probably many places where it is possible to shore dive with Thornback
skates. In southern Corwall around April the estuary of the Helford river is a
good place to try. For convenience Porthkerris
Divers can drop you in the middle
of the river which is only about 10m deep. The tide will then carry you in or
out of the river mouth. It is best to choose an incoming tide when the water is
clearest. It is also possible to gain entry from the shore to this same area but
the incoming tide may mean that exiting in the same spot is tricky.
