Apo Reef, Sulu Sea -- Unidentified comb jelly (ctenophore) floating in the open water, possibly a lobate as the two clearly visible lobes imply.<br />
Ctenophores are found in most marine environments, from polar waters to the tropics, near coasts and in mid-ocean, from the surface waters to the ocean depths. No ctenophores have been found in fresh water.<br />
Almost all ctenophores are predators. If food is plentiful, they can eat 10 times their own weight per day! Surface-water species prey on zooplankton (planktonic animals) ranging in size from microscopic molluscs and fish larvae, to small adult crustaceans such as copepods, amphipods, and even krill.
