the fish and invertebrates you selected after the nitrogen cycling process. I personally selected a maroon clownfish with two anemones. I also chose 5 sergeant majors‚ 2 bleenies and a yellow tang. 2. What changes did you make to your reef tank during the 12 weeks and why did you make them? After I selected my fish‚ I noticed that the tank began to grow algae. The next time I selected fish and invertebrates‚ I chose to add cleaner shrimp and snails to my tank. The pH then started

Description: The rainbow parrotfish is the largest fish in the Atlantic to eat plants. Males can grow to lengths of 1.2 meters‚ or almost 4 feet long. There are two forms of males. “Initial phase” is the phase when males are drab in color and have a similar appearance to females. In the “terminal phase”‚ males are neon and rainbow colored; this is where their name comes from. The fins are orange with streaks of green branching towards the back and tail. They have teeth that are merged to form a tough

frame by frame. According to (Endangered Species International [ESI]‚2011) Dynamite fishing (homemade bomb) is set off under water to kill fish for easy collection. Dynamite fishing has contributed to massive destruction of Southeast Asian coral reefs over the past 20 years. Large blasted areas are very slow to recover because corals have difficulty establishing on loose or sandy substrate. In southern Philippines‚ between Malaysia (Borneo) and Philippines (Palawan) illegal dynamite fishing is still

(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

ecology‚ Chu said. Clusters of delicate marine organisms form coral reefs in a process that may take millions of years. The reefs are built up from the calcium carbonate‚ secreted by tiny animals which secrete the bone like material as an exoskeleton. Often called the rainforests of the sea‚ coral reefs are some of the most diverse ecosystems on the planet. Occupying an area around the globe half the area of France‚ reefs are home to a quarter of all marine species. Most commonly found in tropical

Sea Stars (no longer considered called Star Fishes) are marine animals‚ part of the class Asteroidea. They are carnivorous invertebrates and can live up to 35 years. Despite the number of arms on a sea star averaging 5‚ they can grow up to 40 limbs. Sea Stars can be found almost anywhere but those located in the Pacific Ocean are getting hit with a mysterious condition. This condition starts out as a white or black lesion on the sea star’s body. From there‚ it spreads all over the body‚ causing

October 14‚ 2011 Warming Up to the Truth Being an avid hydrophile‚ I wanted to explore a topic that involved the world of life in the ocean. This allowed me start wondering about coral reefs inside the ocean and caused me to raise the question about how and why some of these become bleached. A number of coral reefs that have been bleached lasted such a long time as luminous organisms filled with color and beauty before suddenly turning white and dull. How does something like that last such a long

have studied and drawn up. The problem with taking these very important ions out of the water is that they are one of the two compounds that calcifiers‚ very small organisms‚ need to survive. Calcifiers‚ which are the base of pretty much every coral reef on the planet‚ need to make shells which is part of their colonies skeleton. This leaves a decision for calcifiers to make: should I expend more energy capturing the decreasing amount of carbonate ions or just give up. Studies show that most calcifiers

Pei Yuan 裴淵《廣州記》over a thousand years ago: “The Shanhujhou (Coral Sandbar) is 500 li south of the county (Dongguan‚ Guangdong). People catch fish and harvest coral from the seas there”. Here “Shanhujhou” refers to Dongsha Island and its surrounding reef. According to Ching Dynasty fisherman Liang Sheng‚ by the 1860’s (Tungchih era of the Ching Dynasty) large numbers of fishermen from Guangdong and Hainan were sailing to the area to catch fish‚ harvest kelp and catch sea turtles. Factories built from

Bottom Trawling Imagine a coral reef‚ filled with life‚ being demolished to just bits and pieces. Unfortunantly‚ this is what happens with bottom trawling. Bottom trawling is a major issue because it damages the eco-system and it kills much more than needed. To begin‚ the destruction of bottom trawling is severe. In the process‚ a 5 ton net with weights is trailed along the ocean floor; destroying everything in its path. Fish are swept into this net and coral is completely turned into dust
