MARINE AQUARIUM THE MARINE ENVIRONMENT The stunning beauty and the staggering diversity of animals to be found in and around the world's ocean often defies the imagination. In recent years, interest in marine fish keeping as a hobby has blossomed, and a whole industry has grown up around providing equipment and a variety of livestock. WHAT IS A MARINE FISH? Fish are some of the most adaptable animals on this planet. They occupy nearly every watery niche; saltwater, freshwater, brackish water, hard water, soft water, cold water, lagoons, tropical seas and arctic seas etc. Marine fish, those that survive and multiply in salt water, inhibit a relatively concentrated medium, containing a host of dissolved substances e.g. salt. WHAT IS AN INVERTEBRATE? The term is a convenient, catch - all title, loosely covering all those animals with no backbone and an internal skeleton. Invertebrates range in size from microscopic planktonic animals to giant squid that roam the waters. The range of marine invertebrates is so vast that there is no sea habitat in which they do not occur.
