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

consists primarily of fish including small sharks and rays. Also consume
crustaceans and snails and octopus. At Rangiroa the Blacktip passes out of the
lagoon on the ebbing tide to cruise the reef face. More active during daylight
Recorded litter size 1 - 10. Gestation period 11 - 12 months.
Conservation Status: Considered
'Near Threatened' by the IUCN. In the western North Atlantic this species has
long been important in the recreational fishery and now is a primary target of
the directed commercial fishery along the southeast coast from South Carolina to
Florida and throughout the Gulf of Mexico (Branstetter and Burgess 1996, 1997).
It is the second most important commercially landed species in that region after
the Sandbar Shark (Carcharhinus plumbeus) and its meat is considered superior to
the latter species. In the USA, Blacktip Shark other carcharhinid meat is often
sold under the name ?Blacktip Shark? because of wide consumer preference for the
product. It is a significant constituent of the substantial Mexican shark catch,
from both Atlantic and Pacific coasts. Elsewhere, it is the most commonly caught
species in the large Indian fishery (Hanfee 1996), occasionally caught in the
Mediterranean Sea driftnet fishery (Walker et al. 2005), and surely constitutes
a sizeable portion of the catch in smaller scale and artisanal fisheries
throughout the northern Indian Ocean and South China Sea. In Australia, it
represents a minor component of the shark catch in northern Australia (Last and
Stevens 1994). Blacktip Shark meat is primarily consumed locally and fins are
dried and shipped to the Far East where they are used in preparing shark-fin
soup. In some areas the hides are utilised in preparing leather and the livers
are used to extract oil.

Reaction to divers:Varied. Usually extremely shy but during some
encounters the Blacktip shark can become aggressive making close passes and
Although blacktip sharks are generally unapproachable, during
shark feeds in Aliwal Shoal, South Africa, blacktip sharks will either
ignore divers completely or investigate them.
There are a number of operators that feed the sharks and the different operators
often feed in close proximity to one another. This cooperative arrangement
keeps the sharks in one spot rather than splitting the resident populations in
