Organisms living between tides are uniquely adapted for the life in the environment whether it be high, mid or low tide. As marine animals, they need to be in seawater for in order to feed, respire, excrete, and reproduce and disperse their offspring’s. But other marine animals do not. They all have special adaptations that allow them to live in their environment. Distribution The distribution pattern shown on the rocky shore is zonation. Zonation is a horizontal band of distribution of organisms along the ground. Different substrates and the tide will affect the zonation patterns. Blue Tubeworm The Blue Tubeworm is found in mid to low tide, never high tide and they are found under rocks on the rocky shore. From my graph we can also see that the environment substrate contains on cobble (medium sized rocks) and sand. Also we can see that the temperature is always colder under the rock than above it. These Abiotic factors have caused the distribution patterns shown on my graph. The blue tubeworm has gills that are flower-like and are both used for respiration and filter feeding. Algae grow on the rocks and other algae resources are delivered across the shore twice a day. This is microscopic plant plankton which blue tubeworms use their gills to filter plankton on of the algae. Filter feeding is a reliable food source as the sea comes up the shore twice a day and living in low tide covered in water al day. Since the tubeworm is a filter feeder this is one adaptation that enables it to survive in the environment from mid to low tide. The tubeworm lives in mid to low tide underneath rocks. This is because rock surfaces provide a almost stable environment for the tubeworm to attach onto. Slips between and under rocks provides the tube worm with a safe environment that will stop it from the heating and drying effects from the sun and the wind, protection from breaking waves and a safe place from large predators. It is also a cool and moist environment under the rocks. There is competiti
