The Indian Ocean - Eels and Rays
Moray eels are common reef predators, usually remaining hidden during the
day with only their heads showing from crevices in the coral. Although rather heavily
built, they are extremely graceful swimmers. They have tough, thick skin and
conspicuous teeth. A common size is about 80 centimeters (32 inches), but lengths
of up to 240 centimeters (almost 8 feet) have been reported and 120 centimeters (4
feet) is not uncommon. I once saw a Moray that was roughly 180 centimeters (6 feet)
long and as thick as a man's thigh in relatively shallow water. It really is an
impressive sight. Although not generally aggressive, Morays should not be provoked.
The section on Potential Hazards deals more with this
subject.
A generally unappreciated group of reef inhabitants, Stingrays are graceful
swimmers and enjoyable to watch. They are really only a threat when they lie half-buried
in the sand in shallow water. Shuffling your feet through the sand is usually enough
to scare them off, a topic covered further in the Potential
Hazards section. When swimming over sandy patches it is often possible to see
the outlines of rays in the sand and, if you are fortunate, one will emerge and swim
away while you watch.
Closely related to the Morays, Electric rays are equipped with small electric
organs on either side of their disc-shaped body. Used mainly as a defensive mechanism,
the organs can give a sharp shock. Although not as common as their cousins, Electric
rays can be seen in most of Kenya's reef areas and coral gardens.
