Dugong
Taken at Abu Dabab, Egyptian Red Sea.
Also known as a sea cow, Dugong's feed in the seagrass
beds of the Indo-Pacific. They are the only
herbivorous, truly marine mammal. (The related manatee
spends some of its life in fresh water.)
Being a slow swimmer, you'll find dugongs in sheltered
lagoons and bays in warm water such as are found in
the Red Sea (eg Marsa Alam), East Africa, the Philippines,
and Australia. They have dense, massive bones, which
help to keep them submerged. Their lungs lie along their
back and act like floats, keeping them horizontal in the
water. They can eat as much as 40 kg (88 lb) of seagrass
a day, leaving distinctive troughs in seagrass meadows.
Dugongs are thought to use the "lek system" whereby
males establish and defend courtship territories
in traditional areas where females come only to mate.
More pictures of Dugongs are in the Red Sea rooms of our photo gallery.
