Part of the appeal of keeping a marine reef aquarium is being able to include a diverse array of organisms, and perhaps even creating a self-sustaining ecosystem. In this section you will find all kinds of invertebrates (and others), many of which perform a critical role in such a system. In many cases though, it is critical to understand all aspects of such an organism’s behaviour and how it will interact with others in closed system. The galleries are organised in broad taxonomic order with the aim of showing how certain organisms are related to each-other, and illuminating the subtle differences that separate them.
