ABOUT ELASMODIVER

E-MAIL ELASMODIVER

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 There is a large library of reviewed shark books, a constantly outdated shark taxonomy page, a monster list of shark links, and deeper in the site there are numerous articles and stories about shark encounters.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.

JENKINS WHIPRAY

View all available Jenkins Whipray Pictures in the SHARKIVE

Common Names: Jenkins' whipray, Roughback stingray

Latin Name: Himantura jenkinsii  

Family: Dasyatidae  

Identification: Rhomboid disc with rounded tips. Anterior margin almost straight. Dorsum yellowish to brown to tan sometimes with richer mottling towards edges and a distinct white margin. Tail whip-like with no finfolds tapering to a dark grey or black. One to three barbs. Row of enlarged denticles running from behind head along tail. 

Size: Max disc width 105cm  

Habitat: Prefers coastal lagoons with sandy or silty bottoms. Sometimes found adjacent to rocky reefs.   

Abundance and distribution: Indo Pacific region from Southern Africa to Australia. In Australian waters from Coral bay around the north coast to Cape Tribulation.  

Behavior: 

Reproduction: Ovoviviparous  

Observations:  

Photographs: Exmouth Navy Pier, W.A.  

Similar species: The Australian book of Fishes lists a similar species living in the region. In the text of this book the Jenkins' whipray is listed as having a distinctive white tail barb. This suggests that the species photographed above may in fact have been misidentified.

Reaction to divers:  I found this ray milling around under a school of baitfish. It was fine with my presence until I approached within a few feet. 

Diving logistics: Often spotted at the pier in Exmouth, W.A.  and at other reef dives in the area. Contact Exmouth Dive Centre for more information.
