The two phyla Cnidaria and Ctentophora makeup the radiate animals. Most radiates have tentacles or oral extensible projections around the oral end that are armed with cells that may function in defense and capture prey. The cells found within the tentacles are structurally and functionally unique to each phylum‚ such as the cindocytes in Cnidarians and colloblasts in Ctenophores. Cnidarians capture prey with special stinging cells called cindocytes. These cells are found throughout the epidermis

Stepan Zhigulin Research Assignment Great Barrier Reef Intro: Coral reefs are like the rainforests of the sea‚ and like those here on land they are being destroyed. But why should you care? Just imagine scuba diving around the corals of the Great Barrier Reef. You are now probably picturing vibrant colours and a bustling ecosystem.

Reefs are very delicate and need very precise conditions to live and grow‚ the amount of rain that is associated with intense low systems can flood the reef with fresh water and reduce the salinity levels. During the storms the turbidly of the water also increases so the sunlight cannot reach the coral reducing its ability to produce

Effects of climate change on Great Barrier Reek Rising sea temperature Rising sea temperatures have adverse effects on the Great Barrier Reef (Johnson and Marshal 2007). According to Johanna and Marshal (2007)‚ increased temperature has a significant role in destroying aquatic life because sea animals have a particular body heat limit to survive in the ocean. As a result of enhanced heat‚ this limit has extended beyond that limit (Laugh and Hobdy 2011). For example‚ 8 years ago summer weather was

entire ref is a marine park with zones that have different uses of water activities with the exception of fishing or collecting. These activities extend to the actual life in the reef. The corals are an animal in the jellyfish family‚ but they contain a solid limestone skeleton. During the day‚ the coral put themselves into the form of the skeleton to camouflage as a rock to hide from their predators. The plants of the reef are not very visible‚ but are important food to the life that lives
