Echinoderms, Hemichordates

write a short essay on the biology and ecological role of the crown-of-thorns sea star (Acanthaster planci). This sea star feeds on the polyps of stony corals and can cause a great deal of damage to coral reefs if left unchecked. In your essay, describe its habitat, geographic distribution, feeding (food source and how it feeds), and life cycle (including reproduction). Also explain its ecological impact, the causes for population outbreaks, and how populations are controlled. You will need to do outside research for this.

Include a diagram of the life cycle of the crown-of-thorns starfish for up to 3 extra credit points (artistic creativity is encouraged!)
