WHAT IS ELASMODIVER?

Not just a huge collection of Shark Pictures: Elasmodiver.com contains images of sharks, skates, rays, and a few 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 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 accessed here:

PELAGIC STINGRAY

View all available Pelagic Stingray Pictures in the Shark Pictures Database

Common English Names: Pelagic stingray, Violet stingray, Blue stingray, Guilers stingray.

Latin Name: Dasyatis violacea. Note: some scientists consider the pelagic stingray to be distinct enough to warrant its own genus. Hence it is also listed as Pteroplatytrygon violacea.

Family: Dasyatidae.

Identification: Romboid disc (kite shaped) with broadly rounded anterior margin. Posterior marging of disc much straighter and tapering towards tail. Tail very long with long ventral finfold. Dorsal finfold absent. One long tail sting usually visible. Dorsum lavender, violet or dark purple. Ventrum also light or dark violet. In individuals with lighter coloration ventrum may darken towards margin. Eyes flush with disc i.e. not protruding.

Size: Maximum disc width about 80cm.

Habitat: surface to 381m. A wide ranging pelagic species (probably the only one among the dasyatid rays) that may be found on the substrate or free swimming in open water.

Abundance and distribution: The pelagic stingray is probably circumglobal in tropical and warmer subtropical and temperate seas. In Eastern Atlantic there are scattered reports from the southern Mediterranean, Cape Verde, to Southern Africa. In eastern Pacific from California, throughout Baja and Galapagos. Also Chile.

Diet: Coelenterates (jellyfish and medusae), crustaceans, oceanic squid and fishes. Occasionally caught on long-lines baited with mackeral in the Sea of Cortez.

Behavior: The Pelagic stingray swims in the open ocean unlike most whiptail stingrays. It also feeds on the bottom.

Reproduction: Ovoviviparous.

Photographs: Sea of Cortez, La Paz, Baja, Mexico.

Similar species: Many whiptail stingrays have overlapping ranges with the Pelagic or Violet stingray. Most can be distinguished by their more sedentary lifestyle. Physical identification is best based on violet coloration and non protruding eyes of the Pelagic stingray; both unusual characteristics.

Reaction to divers: Quickly swims away.

Diving logistics: The Pelagic stingray is very rarely encountered by divers. The images shown here were taken of a specimen that was released by artesanal longline shark fishermen.

Reports of Pelagic stingray sightings would be very welcome: email elasmodiver
