The whale shark is a the biggest
shark and the biggest fish. It is NOT a whale. It has a huge mouth which can be
up to 4 feet (1.4 m) wide. Its mouth is at the very front of its head (not on
the underside of the head like in most sharks). It has a wide, flat head, a
rounded snout, small eyes, 5 very large gill slits, 2 dorsal fins (on its back)
and 2 pectoral fins (on its sides). The spiracle (a vestigial first gill slit
used for breathing when the shark is resting on the sea floor) is located just
behind the shark's eye. Its tail has a top fin much larger than the lower fin.
The whale shark has distinctive light-yellow markings (random stripes and dots)
on its very thick dark gray skin. Its skin is up to 4 inches (10 cm) thick.
There are three prominent ridges running along each side of the shark's body.
The whale shark does not seem to be very bothered by divers and will often let
them get very close and not move away. If they get upset by a persons behavior
they will sink down further in the water or go faster in the water. I have heard
of a Japanese diver did once manage to get sucked into a Whale shark's
mouth but was quickly spat out again
