Anemones & Sponges.

Anemones are larger forms of coral polyps without a hard skeleton. Anemones attach themselves to hard surfaces by means of a disc at their lower end. Some of the most commonly seen are those that have a symbiotic relationship with damselfish like the so called 'clownfish'. The anemonefish obtains protection from predators amongst the stinging tentacles while the anemone benefits from being kept clean. The anemonefish avoid being stung themselves through a combination of an unusual swimming pattern and the chemicals in their mucus coat. Sponges come in various shape, sizes and colours. One of the largest and reaching over a meter in height is the giant Barrel sponge, Xestospongia testudinaria. For more information on anemones or sponges you can go to these external websites:
