Biological Study Of Blacktip Reef Sharks

Sharks are one of the oceans top predators. They vary in size from the extremely small dwarf shark, to the colossal whale shark. Sharks can be found all across the world’s oceans, from the tropic waters of Hawaii to the sub zero temperatures in the Artic oceans. Of the hundreds of sharks a select few species have actually been recorded in the Artic. Of these few, only three of them spend the majority of their time in these harsh, freezing waters. These sharks are the Greenland, Pacific Sleeper, and Salmon sharks.

Throughout the early Paleozoic and Mesozoic ages, the major sharks belonged to a set called Hybodontoidea. They had fins and bony structure

For this discussion, I chose to examine the reproductive nature of mountain lions and hammer head sharks. Mountain lions are solitary cats that live in various mountainous regions of north and south America, but a male and female come together socially in order to mate during the 3-10 day estrus period. Due to their solitary nature, mountain lions rely on scent marking in different territory as well as a mating call of the female in order to initiate the potential for sex. Typically, when a male and female find each other; they spend several days together during the mating period and he may hunt for her and run mating circles around her. Mountain lions are polygynous and both the males and females will mate with multiple individuals throughout

The Mako shark is a very unique species of cartilaginous fish in the Lamnidae family (Col-Spector, Audrey, “MAKO SHARK- Enchanted Learning Software"). This pelagic swimmer is the fastest shark that has ever been observed in the ocean, clocking in at speeds up to 60 mph (Col-Spector). Its streamlined body allows it to swim at faster speeds than most other fish, making it a highly successful predator. “Schooling fish, including tuna, herring, mackerel, swordfish, and porpoise” are popular among the diet of the Makos (Col-Spector). Although they like to prey specifically on schooling fish, Makos eat just about anything they come across (Col-Spector). The Mako sharks physical features and social characteristics is what sets it apart from other species of the deep.

This article talks about what sharks does in order to survive and what are they capable of doing. According to the article, sharks do not sleep; but rather, they have rest periods throughout their day. Sharks are capable of hearing anything below 1000 Hertz and can also swim up to 20 mph. Sharks skeleton is made up of cartilage rather than bone. According to the article, cartilages are lighter than bones. What keep them from floating are their large livers. Sharks can gather and keep the air into their stomach to keep them from floating.

Pacific sleeper sharks, which are also known scavengers, can glide through the water with little body movement and little hydrodynamic noise making them successful predators. They feed by suction and cutting of their prey. They have large mouths that can inhale prey and their teeth cut up any pieces that are too large to swallow. They show a characteristic rolling motion of the head when feeding. Only in Alaska has the shark's diet been studied - most sharks' stomachs contain remains of giant Pacific octopus. They are also known to feed on bottom-dwelling teleost fishes as well as soles, flounders, Alaska pollock, rockfishes, shrimps, hermit crabs, and even marine snails. Larger Pacific sleeper sharks are also found to feed on fast swimming

Who wouldn’t want a Hammerhead Shark as a pet? Even though I think sharks are awesome, and other people agree there’s a few little things you might want to consider before you think you could have one as your man’s best friend. The rest of this paper is about the reasons why you shouldn’t have a Hammerhead Shark as your new BFWF. (Best Friend With Fins.)

Bull sharks are large sharks that prefer shallow waters less than 100 feet deep. They are often found in murky waters. This is a perfect recipe for shark attacks, as bull sharks prefer habitats where humans are swimming, wading or fishing.

Sharks are some of the world's most dangerous and efficient predators, known for dominating the oceans for millions of years. Thanks to movie classics like Jaws they are often exclusively perceived as large, powerful, killing machines, but the truth is sharks come in a wide range of shapes and sizes. Recently, scientists found the carcass of what's considered the smallest shark in the world. The distinctive “pocket shark” was discovered off the Gulf Coast, and is the second specimen ever found.

The black tip shark the biggest black tip shark is around 8.4 feet the average size is 4.9 feet and at birth is 15-28 inches most black tip sharks stay in shallow clear water they are mostly near humans swimming sites

There are two different species of Mako sharks, one is the long finned and the short finned Mako shark. The long finned Mako shark can be up to 14ft. The short finned shark lives in warm temperature water between 50 degrees north and 50 degrees south. The Mako sharks can be found near Australia and New Zealand they live out in the open oceans in deep waters down too 500 meters of depth. Mako sharks can not live older than 45 years. It is most likely to use it’s long sharp teeth to bite anything that is a threat to it or anything near it. The sharks inhabit all the temperatures in the world , with larger concentrations in the Pacific Atlantic and and indian oceans.

lthough sharks can dive to a depth of 200 feet, they tend to stay in shallower water. Hunt, blacktip sharks will wait schools of fish to a sharp decline in the ridge or cliff or the ocean, or when there is a change in current water --- these are the areas where schools of fish are more easily captured and eaten. Like other sharks, blacktip sharks love a diverse number of species, are less numerous than their prey and usually are not preyed upon themselves, making them Apex predators.

The Whitetip shark, for example, lives In deep water where it is hard to find food it must be ready to catch food. The shark has extremely tense senses, so that it can sense the slightest movement and easily catch the prey easily.

Also identified as the Triaenodon Obesus, the Whitetip Reef Shark is one of the most populous sharks in the Indo-Pacific, along with the Gray Reef and Blacktip Reef sharks. The Whitetip Reef Shark grows up to about eight-foot-long and weighs about 44 lbs. It has a gray complexion; distinct gills and its dorsal and caudal fins have a white tip. They also have large eyes that enable them to see in little light. The eyes of the Whitetip Reef Shark along with their sonic senses and ability to use the ampullae of Lorenzini in their snout to detect the electrical charges of their prey is beneficial when they are hunting at night. The Whitetip Reef Shark is found almost exclusively in the caves and crevices of the coral reefs throughout the Indo-Pacific.

Wildlife biology is a field of biology in which land animals are studied. It deals with all animals with backbones and studies individual species of wildlife, their habitats, and surrounding ecosystems (Fitzgerald). It also studies how animals may interact with their ecosystem. Without wildlife biology we would not have extensive knowledge of other animal species, and how they could be linked to humans.
