Elasmodiver contains photos of sharks, skates, rays, and chimaera's
from around the world. Elasmodiver began as a simple web based
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.
There are 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

Blacknose shark is a much faster swimmer than the
Caribbean reef. This may reflect its personality or may be due to it being in
close proximity to the Caribbean reef sharks.

Reaction to divers:
Unlikely to get close enough for divers to identify underwater, without the use
of chum. In St Maarten, Blacknose sharks regularly approach the feeder, but hang
back if larger sharks are present. When they have the feed to themselves, they
sometimes become very aggressive.
Blacknose shark are rarely seen. Doc Gruber's shark lab in Bimini, conducts a
feed where Blacknose sharks are present, but the best location to reliably see
them is the shark feed conducted by Dive Safaris in St Maarten, Netherland
Antilles. The feed is in 65ft of water and is conducted by a chain mail sleeved
shark feeder. Boats leave the dock for the short ride to Big Mamas Reef a few
times a week. Dive Safaris is the pioneer of shark feeding in this area.
