Not just Shark
Pictures: Elasmodiver contains photos of sharks, skates, rays, and
chimaera's from around the world. Elasmodiver began as a simple web
based shark field guide 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
There are now
more than 5000 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 accessed here:

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.
