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

near tip of snout, convex around head and have a second more defined concavity
behind head before extending outward to free tips. Trailing edge of pectorals

lower back along tail. Dorsum shades of brown with subtle dark and/or pale spots.

seen lying motionless on substrate or under sand with eyes protruding but occasionally seen actively foraging
over soft bottoms. May occasionally enter shallows in search of food.
Lays flattened egg capsule with hooked extensions on corners.
Reaction to divers: Very
docile. Remains motionless unless molested. Try not to hover directly above the
body as this may cause it to bolt.
Rarely seen at a few locations along the North Pacific coastline. The photograph
above was taken in November at Deep Cove, Vancouver Island in110ft of water on
gently sloping silt far from any walls or reef structure. Anyone finding a Longnose skate whilst diving is encouraged to
contact me in order to built an information base of sightings. Useful
information would include depth, time of year, and bottom composition.
