1.0 INTRODUCTION
Animals that lack backbones are known as invertebrates. Over 98% of species on Earth are invertebrates that rely on other strategies than a backbone for support such as hydrostatic pressure, exoskeletons, shells, and in some, even glass spicules. Some invertebrate phyla have only one species, while others like Arthropoda include more than 83% of all described animal species with over a million species. The most common marine invertebrates are sponges, cnidarians, marine worms, lophophorates, mollusks, arthropods, echinoderms and the hemichordates.
2.0 METHODOLOGY
A species of invertebrates were observed and identified along and surround a 50m transect line.
3.0 RESULTS AND DISCUSSION
There are overall 6 species of invertebrates observed at the site.

Christmas tree worm
Giant Clamp
Sea cucumber
Sea star
sponge
Sea worm
Tunicates
