Though sea anemones may resemble marine plants, they are actually considered to be animals, akin to jellyfish and corals. Whilst firmly affixed to the seabed, they utilise their motile, stinging tentacles to paralyse unwary, small fish, which they then ingest. Some small fish however, such as clownfish and cardinalfish (both of which are featured in today's set of images), have developed interesting mechanisms that effectively neutralise the sea anemones' sting, enabling them to live tranquilly amongst the sea anemones' tentacles, thereby acquiring in this way sanctuary from their predators.
