Not just Shark Pictures: Elasmodiver contains photos of sharks, skates, rays, and chimaera's from around the world. It began as a simple web based field guide to help divers find the best places to encounter different species of sharks and rays but it has slowly evolved into a much larger project containing information on all aspects of shark diving and photography. There are now more than a thousand shark pictures  and sections on shark evolution, biology, and conservation. There is a large library of reviewed shark books, a constantly outdated shark taxonomy page, a monster list of shark links, and deeper in the site there are numerous articles and stories about shark encounters.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:

ELASMODIVER EXPANDED

If you're looking for a broader range of marine life pictures the following links represent a new area that contains pictures on other marine organisms and on marine habitats. This expansion of Elasmodiver is in its first stages but will eventually include pages on everything from sea stars to nudibranches. Creating this portal will take time and for now it consists of a token offering of fish pictures. Please return regularly to enjoy the progress.

View more Sinclairs Stingaree Pictures in the SHARKIVE

Common Names: Sinclair's stingaree, Spotted stingaree, Sinclairs stingray, Circular stingaree.

Latin Name: Urolophus sp. or possibly Urolophus gigas.

Family: Urolophidae

Identification: Disc circular  with small point on snout. Light grey dorsum with dark patches. Light ringed spot at centre of central dark patch on back surrounded by a circle of light ringed spots. More dark and light spots moving outwards but fading towards disc margin. Vague spots extend along tail. This may be the western color variation of the Spotted stingaree (Urolophus gigas), a juvenile version of U. gigas, or a distinct species.

Size: Maximum length at least 60cm.

Habitat: 5 - 120m. Occasionally seen on rocky offshore reefs.

Abundance and distribution: Rottnest Island south to Esperance, Western Australia. 

Behavior: Remains motionless on reef during the day.

Reproduction: Ovoviviparous.

Observations:

Photographs: Albany, Western Australia.

Similar species: Circular stingaree - Urobatis circularis has similar ringed spots but is distingiushed by lack of dark bat-shaped patches. Also shares its range with the Spotted stingaree - Urolophus gigas (distinguished by broken spots on more uniform background). May be a color variant of the same species.

Reaction to divers: Very patient when approached closely on rebreather.  

Diving logistics: Divers occasionally encounter this species while exploring Michaelmus and Breaksea Islands close to Albany, Western Australia.  Uwe at Albany Dive runs daily charters to the islands and is always willing to help look for sharks and rays.
