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
flattened sharklike body. Elongated flattened rostrum (saw) accounts for about
1/3 of overall length. Saw contains 24 to 34 pairs of rostral teeth which
are further apart near the base of the rostrum.
First dorsal fin originates behind
pelvic fins. Lower caudal lobe is greatly reduced.
Sand and mud bottoms in estuaries, bays, and lagoons. Also in fresh or brackish
water environments in lakes and rivers.
Abundance and distribution:
Uncommon due to habitat loss and over fishing. Easily caught in fishing nets
where removal without injury to the animal is difficult. Also previously hunted
for its saw which was sold in curio shops. Northern Indian Ocean and Western
Pacific from South Africa to Australia.
into schools of fish and thrashes its saw from side to side, wounding and
killing the fish which it then recovers. May also use its saw to dig for crustaceans
and mollusks in the sediment.
Young are born with flexible rostrums in which the teeth are covered
with a sheath of skin to avoid injury to the mother. After birth the
rostrum unrolls and hardens.
The Green Sawfish shares its range with at least 3 other species. The Dwarf
Sawfish (Pristis clavata) has a rounder head and evenly spaced rostral teeth,
the Narrow Sawfish (Anoxypristis cuspidata) has a much narrower rostrum, and the
Freshwater or Broadbill Sawfish (Pristis microdon) has a distinct lower tail
lobe, a broader rostral base, and evenly spaced rostral teeth with the leading
pair angled forward.
Reaction to divers:
There are no locations that I know of where divers can reliably find Green Sawfish due to their rarity and preference for turbid environments.
Any information on sightings of this species by divers and hikers would be very
