pederson shrimp on a tentacal tip of giant sea anemone (ondylactis gigantae)

Sea anemones have been known to scientists for over 150 years. They were first described in 1868 as a host or Habitat by Dr Cuthbert Collingwood in his book "Rambles Of A Naturalist On The Shores And Waters Of The China Sea. Anemones can be found in warm shallow waters around the world. There are nearly a thousand species. Some host different shrimps and crabs. Only nine host fish. Nematocysts are cells located in the tip of the anemone providing it with its poisonous stinging substance for protection and capturing prey. Within this anemone lives a pederson shrimp. They live in what's called a symbiotic or mutualistic relationship. It is unknown whether this relationship is obligatory (needed for survival) or facultatively (by choice), but in any case, the anemone does not sting the shrimp. It is known that the shrimp keeps the anemone clean of dead cells and debris and the anemone gives the shrimp a protective home for shelter. This is one of the few true mutualistic relationships found in nature.
