Names and Classification (Istiophorus albicans) Atlantic Sailfish Synonyms: ocean gar, ocean guard, Pacific sailfish, and sailfish. Other common names are abanico (Spanish), aguja (Spanish), aguja de abanico (Spanish), aguja vela (Spanish), atlanticheskii parusnik (Russian) Family: Istiophoridae (sailfish) Description The Sailfish (Istiophorus albicans) is a long slender fish, with a large dorsal fin. It is most recognizable when its dorsal fin is extended, looking like a boat with a wide mainsail. The sailfish is dark blue dorsally and silver ventrally. On its sides rows of longitudinal stripes consisting of small blue dots (ARKive 2010).
The Sharks can grow up to 16 feet long. They have pectoral fins, dorsal fins, and a vertical tail. The skin of sharks is very rough and made up of millions of sharp scales. Sharks have gills for breathing. What 's can be up to 3,000 pounds.
The female must be careful not to nest too far from the ocean, for she risks the hatchlings being attacked by terrestrial predators or being unable to locate the shoreline. However, if she nests too near to the shoreline, she risks her babies being washed away by the tidal movements before they are fully incubated. The temperature of the sand is also important to determining incubation. The hotter the sand is in the nest, the quicker the embryos tend to develop. Colder sand usually results in more male Loggerheads, as well (Miller, Limpus, Godfrey, 2003).
There are 2 major groups. Toothed whales include 2 families, the beaked and bottlenose whales and the sperm whale, the white whales and the narwhal. They catch fast-moving prey and they have a single blowhole and wide throat. Toothless whales, there are 3 families of baleen whales, the right whale family, the gray whale family and the Rorqual family is the most familiar of the large whales. They lack teeth but have brushlike sheets of a horny material called baleen.
The skin assists in homeostasis. It does this by reacting differently to hot and cold conditions so that the inner body temperature remains more or less constant. Homeotherms (warm-blooded) maintain a constant body temperature regardless of the environment. In the skin of homeotherms, particularly in the scalp, palms, and soles of humans, there is a large blood supply in the form of arterio-venous plexuses that can deliver a huge amount of blood to the dermis of that area. The control of body temperature is dependent upon a negative feedback system to ensure that there is little fluctuation in the internal body temperature.
In Japan, Nomura’s Jellyfish are called “Echizen kurage” (because it is Japanese). In comparison, Nomura’s Jellyfish has a width that is slightly larger than an average man’s height. The jellyfish can weigh more than 449 pounds as well as grow up to 180cm in diameter. This jellyfish is one of the largest jellyfish on the planet. Found in the Pacific ocean, the jellyfish is often located close by Korea and China.
Each one of theses species is suited for its environment and survival tasks through its adaptations. These three amphibious creatures live in various habitats. The Giant Squid prefers to live as far as three football fields under the ocean surface, “500 to 1,000 meters below” to be exact (Database). Its habitat consists of “continental shelves
Such adaptations as those of the mantis shrimp cannot simply be left unseen, therefore, it’s best to explore what may be one of the world’s most extraordinary organisms. First and foremost, the evolutionary history of the mantis shrimp is one that has bewildered the scientific community. What creatures could have possibly mutated to create such a distinct aquatic animal? Well, according to Caldwell, a well-known marine biologist and researcher, the mantis shrimp is a mix of over 450 different species (Caldwell)! For example, one animal the mantis shrimp looks very similar to is the lobster.
1. Describe and contrast two hypotheses proposed to explain the high diversity of teleost fish in coral reef habitats. The teleost fish evolved during the Jurassic period more than 150 million years ago which has led to the high diversity of this group. One hypotheses proposed about the high diversity of teleost fish is that there has been extensive gene duplications in the class Actinopterygii. Gene duplication is proven to show that with the more gene duplication events the more diversity that organism will have.
Control systems throughout your body maintain automatic temperature & water at a steady pace, which requires cells to function. Rapid physical activity in hot or cold climates will affect homeostasis as well. It affects you temperature, hydration, blood oxygen levels, and salt levels. The temperature control system in an incubator, are similar to body control systems. Body systems have receptors to detect stimuli, processing centres to receive info and make responses and effectors which produce the response automatically.
