Pulau Mabul, Sabah, Borneo, Malaysia
A saddleback clownfish family takes great care of the carpet anemone that they call home. The family is led by a dominant female, who directs the smaller males to kep the anemone clean of debris. Here, on the sandy flats of Pulau Mabul, there anemone isn't rooted to one spot and is easily pushed around by the current. So, when the matriach is ready to lay her eggs, her subordinates must find a suitably hard and heavy object for her to use. In their quest to find a safe nursery, the clownfish carefully consider anything the current brings into their vicinity, from the shell of a hermit crab to a discarded plastic bottle, before finally wrangling a coconut shell into the safety of the anemone. Once the eggs are laid and fertilised, the male takes on the responsibility of tending to the eggs until they hatch.
