eels are world widespread in warm or tropical seas, where they live mainly in
reefs or other low rocky areas. Their skin does not have scales like other eels, and
their smooth, muscular bodies range up to about 3 m (about 10 ft) long in some
species. They may also be brightly colored. Each of the single pair of gill
openings is small and circular, and the gaping mouth is filled with long, sharp,
slender teeth. (Certain species have teeth modified for crushing hard-shelled
animal forms.) Typically, morays feed at night on other fish and on mollusks.
Despite their appearance, morays usually do not attack unless annoyed; their
bites, however, can be serious.
eel starts its life as a tiny see- through sexless larva in the Coral Sea near
New Guinea. It slowly starts to develop as it moves south with the currents to
New Zealand, Victoria or Tasmania. It takes one to three years for the larvae,
which are about 50 -70 mm. long, to swim 3,000 kilometers down the east coast of
Australia and enter freshwater estuaries. At this stage of their life cycle they
their sex. The larva that travel up stream become females and the ones that stay
in the estuaries become males. After a short period they grow to become elvers
and turn brown in color. They swim to a freshwater dam, creek, stream or lake
and live there for six to thirty-five years. The eel is now fully mature. The
eels grow breeding organs, lose their gut and stop feeding. Before completing
its life cycle the eel starts its long journey back to the coast of New Guinea.
There it spawns and then dies.
