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a large library of reviewed shark books, a constantly outdated shark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:
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.
Identification:
Pectoral fins narrow and pointed. Subrostral lobe (beak) short and rounded.
Dorsum brown with pale blue blotches.
Size: Wing
span to 150cm.
Habitat: Bays,
rocky and coral
reef faces, and sand flats (where it feeds).
Abundance and distribution:
New Zealand and Australia (from Queensland around the southern coast to W.A.)
Behavior:
Often found resting in sand in excavated depressions. Forages in the sand for
shelled mollusks and crabs but will take fish incidentally as shown by the bat
rays at Hamelin Bay (See diving logistics).
Reproduction: Ovoviviparous.
Observations:
Photographs:
Hamelin Bay, W.Australia.
Similar species:
The New Zealand eagle ray (M.tenuicaudatus) is possibly the same species.
Reaction to divers:
Usually difficult to approach except at Hamelin Bay. See Below.
Diving logistics:
By far the best spot to see and photograph Southern bat rays is Hamelin Bay in
W.Australia. Here the presence of scraps in the water has resulted in these and
other ray species becoming desensitized to contact with humans. Waders and
snorkellers are able to feed the rays right from shore. Noone appears to have
been hurt in this activity and the rays that come in to take advantage of the
snacks are able to be petted and hand fed.
