Chapter 1: The Invisible Crowd

One member of the zooplankton family is the foraminifera. It lives within the photic zone because some have dinoflagellates that perform photosynthesis. The foraminifera is found floating through the ocean, and there are actually many different species of foraminifera, some even reside on the sea floor. The foraminifera grows by creating more space in their limestone shells. They’re only about the size of one grain of sand. The foraminifera can obtain energy by expanding its gooey arms out of the limestone encasing to trap smaller organisms.

The mutualistic symbiotic dinoflagellates increase primary productivity. This is done by the foraminifera moving the algae onto the arms of goo,

They can live broadly throughout the ocean on the sea floor from shallow to deep and can live in virtually all terrains: mua, sana, rock, and coral reefs. They resemble the commonly known garden cucumber, as they’re tube-shaped and can be tan, green, black, although they can also be bright blue, purple, or red. The sea cucumber uses its tube feet to slowly transport itself, with a hydraulic system internally working with water. Some filter feed their food while others use tentacles to catch their prey. Sea cucumbers can also physically change their shape to hide from predators, or look less appetizing. It is also able to spit out its organs to slow down their predators and can regenerate them in 3-5 …show more content…
The conch is also a common decoration and used as instruments, tools, and ornate jewelry. The conch is also harvested by humans as a source of protein from their meat, and sold as souvenirs to tourists. The conch begins its life as platonic larvae until it settles on the seafloor, similar to coral’s planula stage.

Chapter 4: The Riddle of the Reef

A large carnivorous predator that is found swimming through coral reefs is the barracuda. This large fish is a widely feared species and has the features of an apex predator. It has a large mouth, a missile-like body, and spikes. They also tend to scare divers by following them, but they are just extremely territorial, trying to protect their home.

Barracudas may be apex predators within coral reefs, but humans will always beat that. Southeast Asia is a main place where coral reef fishes are eaten, including barracudas. The barracuda prevents overpopulation of organisms by consuming them. The barracuda’s main competition is sharks.

    River runoff from the land: Cane farmers in northern Queensland have had to reverse the cycle of the wetlands so that the water leaves the land quickly, in order for their cane crops to survive. The problem with the water leaving quickly, though, is that it drags the topsoil and various other harmful agricultural chemicals with it. That dirty water then filters into the river catchments that feed the Great Barrier Reef. This water turns into mud, algae and bacteria that settle on the living coral organisms. It then smothers the animal and eventually kills it.…

    The Rocky Shore is an ecosystem of great magnitude although it is filled with a number of smaller ecosystems with in that rocky shore. These smaller ecosystems are the tide and rock pools with in the rocky shore and are home to a large variety of different organisms. All these organisms are not there aimlessly, each and every organism affect one another wether it be plankton, seas squirts, red waratahs, wobbegong sharks, blue octopus etc. Even filtering creatures and plankton are a major part of the ecosystem and the food chain at the rocky shore. This is because if any creature gets abolished no matter what it may be then this creature’s predator’s food becomes scarce and this will result in this particular organism getting wiped out and so on and so forth. With in a food chain almost everything has a predator, unless this…

    Cownose Ray Evolution

    Although evidence has shown that there is a recent change in the increase of the cownose ray that has caused a large boom, it's Well known that the cownose ray is a predator of shellfish when the water becomes warm. The marine systems caused by the removal of sharks remain misleading, due to the significant declines in large coastal sharks in the northwest Atlantic Ocean, which caused dramatic increases in abundances of smaller elasmobranchs (referred to as “Macropredators”) over the predation release. The large coastal sharks decline allegedly led to an order of large scale increase in the population of Cownose rays. Thereby the ever-increasing feeding of the cownose ray has led to the concerns for the shellfish populations along the U.S.…

    Parts of their body adapts to being in water like, “Lungs are proportionally much larger than their land based relatives enable them to spend long periods of time under water, from an average of 15-30 minutes to almost two hours,” (Aquarium Of the Pacific - Online Learning Center). That’s one of the adaptations they need so that they can live in the water. They also have adaptations to live on land. This includes, “large belly scales, assist them in moving on land and climbing low hanging tree branches,” (Aquarium Of the Pacific - Online Learning Center). That is how they’re able to move without hurting their bellies, so that they can live in a terrestrial environment. It may seem cool that they have these adaptations, but humans also have them too to survive.…

    Since the 1970’s when the movie Jaws first showed up on big screens around the country, people have been afraid of beaches, in fear of shark attacks. Not only have they been apprehensive about swimming in the ocean, but some have such malicious feelings towards sharks (especially Atlantic White Sharks due to their role in the movie) that they have taken to hunting and killing this already dwindling species. (Earth Island Institute) It is no secret that pollution and overfishing, as well as numerous other factors have caused the biodiversity of marine life to drastically decrease. It is also known that the ocean ecosystem relies much on all members of the food chain- particularly top predators like sharks. Larger sharks,…

    We identified the eubranchipus, a organism with similar characteristics to one of a shrimp. Another name for it would be the fairy shrimp. During this observation, only two eubranchipus were identified. We did not have as many eubranchipus as the other groups but we were able to put one under the microscope. This organism has very fast movement and many legs. Another observation we made was that they swim upside down instead of right side up. Bothe of he fairy shrimps were translucent. The colors of them are determined by the food supply of their environment. These organisms started off as dried out eggs but as soon was we added tap water, it made food sources available in order to survive , therefore allowing the eggs to hatch. On the fifth observation, one of our eubranchipus died as another one grew bigger. The surviving shrimp started off as being 0.8 cm and increased to 1.2 cm. This is probably because of the lack of resources and competition - survival of the fittest. Less protist of the same size were found and the water was more still due to the limited organisms living in it. The population of protists are decreasing because it is the food source of the eubranchipus (also cynobacteria). Again, this is because of the existence of a food…

    Then the primary consumers in the Great Barrier Reef are mostly the green sea turtles and dugongs because they are the herbivores and eat the producers. From there the secondary consumers in the reef would be what eats the primary consumers and these organisms would mostly be the bigger reef fish like the parrot fish, sturgeon fish, and also turtles like the leatherback sea turtle, hawksbill sea turtle, and other organisms like that. Then from there are the tertiary consumers which consume the secondary consumers and some examples of these in the reef are the epaulette shark, whale shark, tiger shark, and other examples like that. The last category of the organisms would be the decomposers which are the organisms that are stay on the bottom of the reef and eat whatever is down there and those are the prawns, sea cucumbers, shrimp, crayfish, crab, and brittle…

    This laboratory is based on a series of famous experiments that were conducted in the 1960’s along the rocky shore of Washington state, in the northwestern United States…The nine species in this laboratory’s simulated rocky intertidal area include three different algae (including one you may have eaten in a Japanese restaurant); three stationary (or “sessile”) filter-feeders; and three mobile consumers (Keystone Predator Student Workbook). In this simulation there are nine different species. The Nori Seaweed, Black Pine, Coral Weed, Mussels, Acorn Barnacles, Gooseneck Barnacles, Whelk, Chiton, and Starfish. The Nori seaweed, Black Pine, and Coral Weed are all algae, which means they live in damp environments and are plant like and have chlorophyll. Having chlorophyll they make their own food through photosynthesis, the fact they can make their own food makes them autotrophs or producers, and are the lowest on the trophic level. The Acorn barnacles, mussels, and gooseneck barnacles are the filter feeders of this environment they do not move. They are the herbivores of this environment and the primary consumers on the trophic level. The whelk, chiton, and starfish are the only mobile species in this environment. Also they are the only carnivores in the environment and are secondary consumers on the trophic level.…

    The Great Barrier Reef supports around 350 species of stony coral and 1,500 species of fish, some of which are sharks. The stony corals that build coral reefs are slow-growing but long-lived corals. Many types of stony corals grow in the Great Barrier Reef, including branching corals, stag horn corals, massive corals, brain corals, plate corals, and mushroom corals .Coral reefs are the most ideal place for marine life to live. The large surface of the coral reef provides natural shelter and food. It is because of this that coral reefs are the homes of the largest ecosystems in the world. Some fish that inhabit The Great Barrier Reef include Damselfish, Wrasse, Butterfly fish, Angelfish, Cardinal Fish, Groupers and Basslets.…
