“Over 200 fish species have been introduced to the United States following importation, many of which threaten ecosystems and infrastructure” (103). When exotic animals are introduced to habitats they did not evolve with, they are without many of the environmental stressors that are placed on native animals, such as predation. When that characteristic is coupled with the fact that some exotic animals may be larger and more aggressive than its ecological counterpart, it becomes easy to see how non-native species out-compete native
Other invasive species may not destroy the habitat, but it can have an impact by killing large numbers of other species. Burmese pythons, for example, are top predators in the Everglades. As such, they have local mammal and bird populations. They are capable of consuming deer and even alligators, these creatures eat virtually any animal they encounter in the Everglades. A number of threatened and endangered bird species have also been found in the digestive tracts of pythons, prompting concern that they could drive some species toward extinction Lampreys in the Great Lake parasitize native fish.
It usually thrives in reefs but it is also easily found in hard bottom areas, mangroves, seagrass flats, and shipwrecks. This beautiful looking fish packs a punch: The fish has venomous spines that deliver an extreme pain that can last for days. In extreme cases, the venom can even cause paralysis. The LIonfish is an apex predator on the reefs using its fins to coral small fish and anything it can fit into it’s mouth into a corner before it strikes quickly swallowing it whole. The lionfish feeds on an array of over 50 species including ecologically and economically important species.
Why is killing sharks bad? Sharks play a vital role in the oceans in a way that the average fish does not. Most sharks serve as top predators at the marine food pyramid, and so play a critical role in ocean ecosystems. Directly or indirectly they regulate the natural balance of these ecosystems, at all levels, and so are an integral part of them. As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes.
After the movie Jaws came out people thought it would be macho to go and hunt sharks. There would be killing tournaments to see who could get the biggest shark. The biggest shark that was ever caught was a 20 foot long great white shark. People are also overfishing sharks. There is a huge problem with finning for shark steaks or shark fin soup.
They are many reasons why species are successful at effectively living in a new environment. Species have many different characteristics that allow them to be successful in its own habitat, some of the characteristics are they have the ability to grow quickly. They have very basic eating diets. The species can spread out too many other environment conditions and survive. For example, Kudzu became known as “The mile a minute vine” and “the line that ate the south” due to its quick growth and widespread takeover.
Background The point of this analysis is to compare the abundance of Stonefly Nymphs in rifles vs. Poles. EXPLAIN The Plecoptera are an order of insects, commonly known as stoneflies. There are around 3,500 species worldwide, with new species still being discovered. Plecoptera are found in both the Southern and Northern Hemispheres and the populations are quite distinct. All species of Plecoptera are intolerant of water pollution and their presence in a stream or still water is usually an indicator of good or excellent water quality.
marine animal I’m researching is The Great White Shark. They are also known as, White Death and White Pointer. Great White Sharks are located off the coast of California, Australia, South Africa and the northern United States. Other continents and countries call them Tommy Sharks, Blue Pointer, Uptail, Maneater, etc. Great White Sharks are mostly infested in the USA and Australia and have caused 188 deaths in total.
Research displays that the rate at which sharks are killed is close to 100 million every year! There are so many causes which assist with Sharks being on the verge of extinction, one of which includes human activities. First and Foremost , Shark finning refers to the removal and retention of shark fins and the discard at sea of the carcass. This means that for commercial purposes poachers cut off the shark 's fin, (while its still living) and tosses it back into the ocean. This is a detrimental problem because unable to swim, the sharks sink to the bottom of the ocean where the remains are eaten by other fish.
So, he armed his men and started shooting the big green giant with there bow and arrows while he cut the ropes off the rocks and slowly started floating away still shooting their bows. Boo got mad... Very mad… He grabbed 17 men off the boat and ripped them apart and ate them all in one bite. He noticed that the boat had started to float away. So, he jumped in the water and swam as fast as a marlin and caught up to it and slammed his fist on the humongous boat.
