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

Eastern Australian angel shark, eastern angel shark, Australian angelshark.
Name: Squatina punctata
Tan to grey flattened body with brown spots and blotches and many scattered
white spots outlined with subtle dark rings. Larger dark spots
form irregular ocelli. Forehead (between widely spaced eyes) concave. Terminal mouth with heavily fringed nasal
barbells and anterior skin
Size: Maximum recorded size of males 110cm.
Max size of females 130cm.
Continental shelf and slope from 60 to 315m. Mostly 130-315m.
The eastern angel shark is restricted to the east coast of Australia. From
Cairns in Northern Queensland down to Lakes Entrance, Victoria.
Angel Sharks are ambush predators that lay in wait partially buried in the sand
until an unsuspecting fish or invertebrate ventures too close. The eastern
Australian angel shark's heavily branched nasal flaps and barbells probably play
a part in enticing prey towards their mouths.
Litter size up to 20.
Listed as VULNERABLE by the IUCN. Quote: 'Heavily fished (utilized trawl bycatch)
in the southern half of its range. A 96% documented decline in CPUE and a
reduction in the mean size of large individuals reported by fishery-independent
trawl surveys between 1976 to 1977 and 1996 to 1997 in fished areas near the
center of the range. This represents only a quarter of the total range of this
endemic, with large areas of its northern range (where the species' abundance is
suspected to be lower than in the central and southern parts of its range)

Australian Angel Sharks overlaps in range between Newcastle NSW and Eastern
Victoria. It can be distinguished by its forehead which is convex rather than
concave. The eastern angel shark also has generally bolder markings. Divers are
far more likely to see Australian angel sharks which live in shallower water
than their eastern cousin.
Reaction to divers:
Unknown. Probably remains motionless relying on camouflage to avoid detection.
Many angel shark species will allow divers to gently waft the sand off of their
backs before they decide to bolt.
Because the eastern angel shark resides in water deeper than 60m, they are
rarely if ever encountered by divers.
