I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
Danafungia scruposa is a species of coral found in the eastern and western Indian Ocean, the eastern central, northwestern and western central Pacific Ocean, Japan, the East China Sea, the Red Sea, and eastern Australia. It is around 25 centimetres (9.8 inches) in diameter and normally consumes a variety of food from bacteria to mesozooplankton measuring 1 mm (0.039 in) in diameter. During an algal bloom in 2009, researchers observed D. scruposa consuming the jellyfish Aurelia aurita, the first time such behaviour had been seen in the wild. This D. scruposa coral was photographed in the Red Sea off the Egyptian coast.Photograph credit: Diego Delso
