The Sharks that I observed in the animal cam at the Blacktip reef exhibit at the National Aquarium in Baltimore is an ecosystem. I saw Blacktip Sharks, Clown Fish along with Manta Rays. They were many more organisms on the cam that I couldn't identify. This shows that there is a biological community. While on the cam I saw that the sharks even though they are predators never ate the smaller organisms it was as if they were protecting the smaller fish. This shows that there is interaction in the ecosystem. In the cam, there were reefs and underwater moss growing on the anemones. It had sunlight and water. This shows that they have a physical environment in the ecosystem because of the sunlight and water along with the reefs. The evidence shows…
They are found all around the equator area . They like the warmer water . They swim far offshore and nearshore too . They are found in the coral reefs too . They live in the tropical climate . They live…
shark to be able to inhabit almost all waters on earth. But, with out salt water they would die due to their cells rupturing because of the lack of salt. The kidneys of the shark are also pretty cool my dude, they can recycle the salt in their body because of another really cool gland located near the tails of the shark my dude. It has been also documented that the shark can live in freshwater for up to six years without any negative effects on the shark's body or health.…
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,…
A head that looks like a hammer, one eye and nostril are located on each side of the head, extra-tall dorsal fins. They grow to about 3 feet (0.9 meters) to 20 feet (6.1 meters). They weigh to about 230-450 kg (500-1000 lbs). They are usually grey, brown, or white. They have smooth skin.…
Most people are afraid of sharks and don’t want anything to do with them but there are people that actually know things about sharks and don’t fear them. Sharks much like people come in all different shapes and sizes and can and do live mainly everywhere. What people don’t know is that sharks are much like people they take care of their young by protecting them, feeding them, teaching them to hunt. They are thought of as cold-blooded killers but they aren’t they just do what they have to do to survive they hunt to eat they can’t go to a grocery store and buy food they have to hunt for it they will eat what they…
The shark is known to be a terror of the ocean that does nothing more than kill human’s, at least this is what was think of these creatures until more research was discovered. The truth is that the shark is a beautiful creature that has more than 440 species that is being hunted to extinction. Not many people are killed by sharks, as it is more common to be killed by a vending machine, than a shark. These creatures do not need to be hunted, as they are already on the verge of extinction.…
There are several different types of sharks in the ocean. And there are strange sharks very, very strange sharks. Deep in the bottom of the ocean house’s the rarest shark man as ever seen or heard of. The Goblin Shark, its other name is “living fossil”. These sharks live in the deepest part of the ocean. They grow huge 10 to 13 feet long.…
Carcharhinus Leucas or bull sharks are the only species of sharks that are able to travel long distances and spend extended periods of time in freshwater environments. Although many people disagree, I believe that one of the bull sharks’ main reason for entering freshwater is to find breeding grounds. There is evidence that supports this theory, and it seems to me a very logical explanation, however it is a controversial concept. In this paper, I will discuss what physical characteristics allow bull sharks to survive in both marine and fresh waters, and attempt to understand whether they do this…
Killer whales feed on sea birds, squid, octopuses, sea turtles, sharks, rays and fish. The killer whale is a toothed whale and is the largest member of the Dolphin family. These large marine mammals easily noticed by their black-and-white coloration, Image result for where do killer whales live. Killer whales are found in the open ocean, but they seem to be most abundant in coastal waters. Killer whales are most abundant in the Pacific…
With research and studies being conducted on both wild and captive Killer Whales, data and information has been generated that adds question to the health issues associated with captivity. “The killer whale (Orcinus orca) has proven to be among the most difficult of all species to hold adequately in zoological facilities. The killer whale is a particularly large-brained and long-lived species who evidences a high degree of social complexity in the wild.” (Noonan) Their behavior and relationships with other whales within the family, known as a pod, creates an immense bond between the animals. Whales that were documented inhabiting the Pacific Northwest, remain in their natal group for most, if not all, of their life. (Robeck) When in captivity,…
The narrator immersed himself in the ocean to escape from his past; he is still dealing with the death of his son and guilt that he was one that killed his own flesh and blood. While in the ocean the narrator briefly describes his swimming technique, he states that he enjoys the feeling of swimming harder underneath the current. He pushes himself harder in the ocean to the point he grasp the concept that in just a matter of seconds a body can easily die as live. Swimming in the ocean with the narrator were jellyfishes and a whale shark. The significant about the whale shark, is it was once alive in the ocean swimming freely than suddenly captured and killed. I believe that the narrator saw as a representation of his son, because similar to…
Killer Whale, largest member of the dolphin family. Killer whales occur in more parts of the world than probably any other cetacean (see Whale). They occur in all oceans, both in the open ocean and close to shore, but are more common in the colder, more productive waters of both hemispheres than in the Tropics. Resident populations may cover an area of several hundred square kilometers. Transient populations often move through an area rapidly, swimming more than 1000 km (more than 600 mi) along a shoreline in a matter of days. Killer whales are black or deep brown overall, with striking white patches above the eye and from the lower jaw to the belly, and a fainter grayish-white saddle patch just under and behind the dorsal fin. Males are somewhat…
Sharks are ovoviviparous, in which the baby shark forms within the female, inside an egg, and hatches inside the female, then the female shark will give live birth. Fertilization occurs inside the female when the male uses its claspers to insert the sperm into the female (Chewning). The total gestation period is about one year, and while in the womb the shark embryos eat the unfertilized eggs, which is a phenomenon called oophagy. Thus the great white shark can produce anywhere from two to fifteen pups. When the pups are born they are generally five feet long and can weight up to eighty pounds. This is the time when the mother swims away from her offspring and the pups are on their own to survive, however, from the one-year gestational period, and the nutrition from it’s brother or sister pup, the young shark is well on its way…
