Dredging can have negative impacts on marine ecosystems by destroying habitats, stirring up sediment that can harm marine life, and altering water flow patterns. Banning dredging can help protect ecosystems and promote sustainable environmental management.
Marine life dies and goes extinct. That's what happens when where they live gets destroyed.
They are dredging Port Phillip Bay to get huge container ships in and out of the bay to get items and food. In result of this they will be destroying thousnads of marine life. I made this map of the dredging plans and where all the marine life reserves are. http://img176.imageshack.us/my.php?image=portphillip.gif&via=tfrog I hope this helped :)
The Spriggina's Habitat is in the shallow, sandy, Marine habitat
Marine
choanoflagellates are sessile marine and in freshwater habitat.
Euplectelea is categorized as Porifera in the Phylum Animalia. Most of the Porifera organisms have a marine habitat except a few. Hence EUPLECTELEA`s habitat is marine.
marine water
When people put salt on the leech the leech dies and the marine leech will survive in the marine habitat.

Marine Ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment).
