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

The egg capsules are laid in pairs and the female then swims around the reef
until the eggs snag on a suitable piece of substrate. 18-20 may be laid during
each breading season. I have had reports of many pairs of dogfish congregating
around shallow sites near the Lizard Peninsula at the beginning of June.

is a common species along the UK coast and is frequently encountered on dives. The
west coast is probably the best place to find them in great numbers. I have seen
them whilst shore diving from Porthkerris, in Helford River, and on the isle of
Skomer in Pembrokeshire. Contact Porthkerris
