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

in small groups. Hunts for reef fishes, crabs, lobsters, and octopus at night.
Litter size 1-5. Gestation period 13 months.
Conservation Status: 'Near Threatened' according to the IUCN. Taken in
line and net trawl fisheries operating in shallow reef areas, this shark has
been recorded as part of the multi-species shark catch taken by tropical
fisheries, e.g. Barnett (1996), Hayes (1996) and Keong (1996). Although its life
history pattern suggests a moderate capacity for rebound (Smith et al. 1998),
heavy fishing pressure inshore and lack of management plan in most places
suggest that this species may be under threat in heavily fished areas, including
remote tropical reefs (Anderson et al.1998).

whitetip reef shark is easily distinguished from other carcharhinids by its
slender body and habits.
There are a number of other whitetipped sharks.
The oceanic whitetip shark Carcharhinus longimanus is much stockier and has long
spatulate pectoral fins.
Reaction to divers:When encountered
at rest generally lifts off the bottom and swims slowly away. May ignore divers
completely if part of a hunting mob. Not considered dangerous unless
speared fish are present at which point it may become aggressive.
whitetip is encountered on a very regular basis on many dives throughout the
tropical Indo Pacific and is usually the most commonly seen shark. At Cocos
Island whitetips are seen at night by divers in marauding packs breaking up the
reef to get at hidden fish and other prey. The Undersea Hunter runs shark diving
expeditions to Cocos throughout the year.
