 Sand
Tiger Shark (Carcharias
taurus) This
species is distinguished by its flattened,
cone-shaped snout, and by its anal and both
dorsal fins being the same size. It is unique among sharks in that it will
come to the surface to take big gulps of air; it
holds the air in its stomach, allowing it to
maintain neutral buoyancy, meaning it does not
have to keep swimming in order to stay afloat. |
 The Bramble
Shark (Echinorhinus brucus)
is distinguished from similar-looking sharks by
having two small dorsal fins located far on the
back just before the tail., as well as the large,
thorn-like denticles that cover its body. |
 The
Whale Shark (Rhincodon
typus) is the largest fish in the sea, being
18-40 feet long and weighing an average of 20.6
tons. In addition to size, the whale shark is
distinguished by its blunt snout and a mouth up
to 4 feet wide at the very front of the head;
most other sharks have a more pointed snout and
the mouth is on the underside of the head. |
 Orangespot
Freshwater Stingray (Potomotrygon
motoro) is found in the shallower waters of the
Amazon River Basin. The barbed spine at the end
of the tail produces a nasty venom which can
cause severe pain to those unfortunate enough to
disturb one of these normally placid animals. |
