Elasmodiver.com contains images of sharks, skates, rays, and a few
chimaera's from around the world. Elasmodiver began as a simple web
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.
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 reef and devoured it.

Henderson Point, Saanich Inlet, Vancouver Island, Canada.
Reaction to divers:
A slow moving species that rarely reacts aggressively to divers but will swim
away when closely approached. Baited encounters at the Seattle Aquarium report
that in these situations the Bluntnose sixgill changes into a lightning fast
sixgill is a difficult shark to encounter outside of the Pacific Northwest as it
remains at great depth. From Washington State up to Northern Vancouver Island it
can be encountered mainly in the summer months. Hornby Island in the Straits of
Georgia between Vancouver Island and the BC mainland is the place best known for
encounters but many divers return frustrated by this illusive shark. Another
good spot for encounters is the fiord north of Victoria known as the Saanich
Inlet. On the west side of the Saanich Peninsula are 3 well known entry points
that each are responsible for Sixgill sightings. Amongst these Henderson Point
has probably seen the most sharks with 15 or more sightings occurring during the
summer of 2004. Shore diving information and air can be had from various dive
shops around Victoria including Ogden Point Dive Centre located at the
Breakwater close to town.
