IN DEEP: Protective strategy for ‘Nemo’ on reefs
THE sea anemone is one of the most recognisable animals divers come across almost on every dive.
Sea anemones commonly found on local reefs are generally brown in colour.
Their tentacles which can grow to about 20 centimetres will instantly retract when touched by a diver.
Sea anemones are harmless to divers.
They form a symbiotic relationship with the clownfish, arguably one of the most popular fish living on coral reefs in the world.
Hollywood made a best-selling movie about a clownfish called Nemo.
When they are young, clownfish will search out a host anemone for protection and will then live among the anemone's tentacles.
While the tentacles of the anemone can be harmful to other fish, the clownfish is immune.
Clownfish found on local reefs are generally orange in colour with three vertical white stripes.
They can grow up to 10 centimetres. The females are larger than the males.
