Elasmodiver.com contains images of sharks, skates, rays, and a few
chimaera's from around the world. Elasmodiver began as a simple web
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.
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
Common Names: Arabian Banded

Maximum disc width at least 62cm.
Found mostly on sand and mud substrates (sometimes adjacent to reefs)
down to 60m.
Indian Ocean. Apparently restricted to the ArabianGulf/Persian
The Arabian banded whipray mostly feeds
Ovoviviparous. Litter size unknown.
The IUCN lists the Arabian Banded Whipray
as LEAST CONCERN. The population is presently stable but
habitat destruction may lead to an eventual reduction. The main
threat to this species is incidental capture in trawl and gillnet
fisheries. Marine habitats in the Gulf are experiencing high levels
of disturbance and quickly deteriorating due to major impacts from
development activities (including dredging and reclamation),
desalination plants, industrial activities, habitat destruction
through the removal of shallow productive areas and major shipping
lanes (Sheppard et al. 2010) which is likely to impact this species.
Dubai, United Arab Emirates.
Maculabatis randalli shares its
range with a number of other dasyatid stingrays, most of which can
be differentiated by their disc shape or the presence of fin-folds
on their tails. Other undescribed, plain coloured maculabatis rays
may be present in the Indian Ocean.
Reaction to divers:
Skittish. Will bolt if closely approached.
This ray is seen by divers in the UAE. Dive shops in Abu Dhabi run to
sites where this ray is occasionally encountered.
