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:

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
