ABOUT ELASMODIVER

BIO OF ANDY MURCH

WHAT IS ELASMODIVER?

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 photography.

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:

Habitat: Prefers offshore islands, sea mounts, drop offs and vertical rocky or coral reefs. To 180m depth.

Abundance and distribution: Circumtropical.

Behavior: Known to exhibit a threat display of head swinging and exaggerated swimming. Often found in loose aggregations. Feeds on reef creatures such as moray eels and other reef fish, cephalopods, and crustaceans. Larger individuals may hunt smaller elasmobranchs and where available also prey on pinnipeds (Galapagos).

Reproduction: Viviparous. Litter size 6 - 16.

Observations:

Photographs: East Africa.

Similar species: Dusky shark (Carcharhinus obscurus) First dorsal originates behind pectoral axis. Snout broadly rounded. Prefers continental coastlines.

Reaction to divers: An extremely inquisitive shark. May persistently circle divers. Respect should be shown around this animal especially larger individuals, however smaller Galapagos sharks may be especially bold occasionally charging divers.

Diving logistics: Although the Galapagos shark is known to occur around the world, it is commonly encountered where it was first recorded at the Galapagos Islands of Ecuador. The shark watchers Handbook lists Gordon Rocks off the North coast of Santa Cruz to be especially good.
