Elasmodiver contains photos of sharks, skates, rays, and chimaera's
from around the world. Elasmodiver began as a simple web based
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.
There are 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

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.
