• INTRODUCTION
• Hook: Imagine a place with no light, so much pressure your skull is caving in, all your bones are being crushed, and fish are staring at you as you scream in pain. This is what it is like at the bottom of the Pelagic zone, where tunas, jellyfish, sharks, and blob fish need to adapt to survive these conditions in their ecosystem.
• Background Knowledge:
• Definition of ecosystem: An ecosystem is a place where all the living and nonliving things are living in a specific environment and interact with each other.
• Info on zone: The Pelagic zone is the largest ocean zone, but it does not hold the most types of ocean creatures.
• Info on zone: The Pelagic zone is also known as the “Open Ocean” as it is located between two continental shelves, in the middle of the ocean.
• Info on zone: As

• Main Point #3 - name/identify the adaptation: the last adaptation of the blob fish is its gelatinous skin.
• Prove It (text evidence…) - describe the adaptation: As stated by nmfs.noaa.gov,” Blob fish has gelatinous skin and its density is slightly lighter than water’s density, making them able to float around in the deep sea instead of spending their energy for swimming.”
• Prove It/Elaborate it (This helps the...because) - explain now the adaptation helps the animal survive: This adaptation helps the blob fish survive by both allowing it to withstand even higher pressures than normal for fish that live at the same depth as the blob fish, and allow it to conserve energy for hunting, instead of spending it for swimming.

• Topic Sentence: There are some environmental threats causing for the blob fish, like pollution, overfishing, and climate

Oxygen breathing lungs are a universal trait of class reptilia. As such, it would have been necessary for the Plesiosauroid - a marine reptile, to return to the ocean surface to inhale air. Oxygen expenditure in reptiles is proportional to strenuosity of locomotion (Frappell, Schultz & Christian, 2002). Therefore the Plesiosauroid must have held physiological traits that enabled the species to avoid oxygen deficit while hunting deep-sea dwelling prey. This essay will outline the hypothesised respiratory, circulatory, pulmonary and sensory attributes of the Plesiosauroid as they relate to diving. These hypotheses will be supported by investigating the physiological adaptations of the Plesiosaur’s biological analogues, and the prospect of similar adaptations in the former will be speculated upon.
An adaptation is the characteristic of an organism that makes it likely to survive. There are three types of adaptations: structural, physiological, and behavioural. Structural adaptations are physical features, physiological adaptations are related to the internal body functions, while behavioural adaptations refer to how organisms respond to stimuli (Beavis 2014). This paper will discuss some adaptations that help koalas and eucalyptus trees survive in their environments.
The problem is that it is difficult to locate the genes that stimulate adaptation for three reasons:
...er. like most pelagic sharks, the hammerhead need to keep moving not just to stay away from the bottom but also to help it breath. if a hammerhead stops swimming it will drown. the hammerheads flat head acts as a wing to keep it from the bottom.
According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.
• Understand the movement of fish. Since small water bodies have limited oxygen supply, fish tend to stay shallower. On the contrary, fish in larger lakes have adequate oxygen supply; hence, fish tend to stay where there is food. The fish may also stay deeper because the temperature of the deep water is slightly higher.
Fish were amongst the first known chordates about 500 million years ago. Therefore, they have a very elaborate and complicated evolutionary history. The first type of fish to appear during the Ordovician era were called Ostracoderms. They had their head and flanks covered with a bony armor while they had a cartilaginous back. The shield was used to keep off predators. The extinction of the Ostracoderms during the Devonian period saw the emergence of Placoderms. These types of fish were also armored, but their functional jaws distinguished them from their predecessors. They also have gills derived from their jaws that took over the specialized role of gaseous exchange. Evolution of
It is important to notice that the opening chapter acts essentially as an introduction to a wider discussion throughout his book. In an effort to give his exploration some order and consistency, Bluestone organizes his discussion under five sections. He identifies five main points, which composes the process of adaptation. Despite these efforts to contain each discussion under such headings, Bluestone’s discussion goes off track during his analysis, which only makes the laws that govern adaptation harder to underst...
An earthquake landed at 9.2 on the Richter scale and the second highest ever recorded initiated a geological uplift of four to five meters (13-16 feet) and captured the fish in newly formed ponds on islands in the Gulf of Alaska, south of Anchorage in 1964. This natural disaster stranded seawater-native fish in new formed freshwater ponds on three different islands. In just decades, the three spine stickleback went through changes in their genes causing their external traits to alter such as, their eyes, shape, color, bone structure and body armor to survive in fresh water after the destructive force. The genome itself is being rapidly reshaped. Stickleback fish can adapt on this time scale because the species as a whole has evolved, over millions
To achieve the ability to such extreme transformation, the puffer fish came through the major evolution of its internal skeleton. Ribs and pelvic part of girdle have been lost and other parts of girdle have been modified to enable the pumping mechanism.
Throughout time, of course, marine biologists have created methods—or “techniques” (163)—that allow such a task to become more straightforward. The method which mainly comes to mind involves close observation of the organism, and noting as much of its minor and major characteristics while attempting to identify it. By recording such details as the organism’s symmetry, general shape, colors, external appearance, internal structure, and measurement, marine scientists can refer back to identification guides to figure out what specific classification their organism fits in, or whether they have the right taxonomy in mind or not (Mertz, Garrison and Baker 163-164). Upon confirming the organism’s identity with the noted characteristics, finding extra information about it becomes much easier
Some diatoms are benthic and live on mud, seaweed, and other surfaces. Other diatoms are wholly plankton and float in the water column. What type of adaptations do you expect each type of diatom to have? In other words, how do some diatoms stay afloat, while others stay attached to the benthos?
The problem I have chosen is the problem of endangered species. An endangered species is a group of organisms that have a risk of becoming extinct. More than 90% of all species that have ever lived on earth has become extinct. Many reasons for this are habitat loss, predators, too few organisms for sustainable reproduction. Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the coast and in the ocean. Rising sea levels can
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
