Lionfish: Invasive Species In The Caribbean Sea

Hammerhead sharks are found in ecosystems in temperate and tropical oceans. They live in these types of oceans, because if it was a colder climate they would die from hypothermia and soon the species would become extinct. These sharks like to stay in schools up to 100 in numbers. The reason they stick together is there is more protection in numbers and they can kill bigger prey like big great white sharks. Next Hammerhead sharks gets there name for its flat shaped head and some people think it is useless to the shark.

But it does however, give us the 3 main suspects. For the tiger shark, they are known “to have a low metabolic rate and doesn't have to feed very often.” (25:15). But is knowing that, gonna keep you from keeping your guards up when in the water? Probably not. But unfortunately, a young girl named bethany hamilton encountered a tiger shark.

If we do not realize this reality, we could lose sharks forever. A monumental reason why I believe that sharks should be protected is because when they attack, it is often a product of mistaken identity. Sharks use electromagnetic pulses to track down prey, therefore their eyesight suffers to a degree. Surfers often resemble seals from the depths of the water. Sharks use their pulses to strike what

There is a higher chance of getting struck by lightning or a vending machine falling on you than getting bitten by a shark. Another factor that goes along with this is that if a person does get bit it is only because the shark is curious and it mistakes you for a fish. Sharks will feel the vibration of you moving around in its lateral line. Sharks strictly feed off of any sea creature not humans, the shark will quickly realize you are not a sea creature when it does bite you and it will most likely go away. The shark myths that exist are all mainly false.

It is believed that sea lions are capable to detect humans by smell over a long distance of hundreds of meters away. The sea lions use their sensitive vibrissae to explore objects on land and in the water. They seek out physical touch with other sea lions and form groups and lye with each other on land. Feeding habits: Sea Lions are carnivorous having fish being their favorite food including herring, mackerel, pompano, salmon, capelin and squid. They also feed on crabs and clams.

Recently, the famous clear waters of Crater Lake and the Mazama Newt that resides there have been threatened by the expanding crayfish population. In 1915, humans wanted to provide food for the non-native fish in the lake, so they introduced crayfish. In addition to threatening the newt, a drastic change in population threatens the magnificent clear waters of Crater Lake. Officials have attempted to place large, metal underwater barriers to try and slow the spread of the crayfish. The 18-inch tall metal barriers would be placed in certain spots around the lake, perpendicular to the shoreline, similar to a wheel and its spokes.

This quote shows that the Tiger shark is an extremely vicious animal that kills numerous innocent beings. The Tiger shark has been brought up a few times already. I think that it will play a big role in the story; I think it will kill Starbuck. Another reason why I think that Starbuck will get eaten is because Starbuck has been hanging around where the Tiger shark has been. Starbuck has been relaxing in the sun and finding food by the island that the Tiger shark has been hanging around.

I think Killer Whales should not be in captivity because, of the injures they can get in their tanks, how they get stressed out and they are better in the wild. The first reason why I think should not be in captivity is of what happens in their tank. The first piece of evidence from the PETA practical “Aquariums and Marine Parks” is that since the tanks for the orcas are usually small for them, they get insane because of the echolocation they use. This makes me think that since their fin sometimes curves, that they would get injured while swimming. In addition, this might make the whale die faster than what they are supposed to live to.

Having effects on local animals starts out with the fact that Burmese pythons are carnivores. Source 1 states,” Burmese pythons are carnivores and survive primarily on small birds and mammals.” (Source 1). This shows how burmese pythons are carnivores and primarily feast on small birds and mammals such as opossums, raccoons, and bobcats, as well as other bird species. As roaming around freely in the Everglades, Burmese pythons don’t have any natural predators. Source 2 states,”With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species.” (Source 2) This shows how without any predators around, Burmese pythons consume and wipe out lots of animals in the Everglades.

Humans are afraid of sharks for various reasons. Some of those reasons are the shark’s size. Humans tend to be afraid of bigger animals, especially when they are known to have killed humans in the past, which is another reason humans are afraid of sharks. One other reason humans are afraid of sharks is because sharks have been misunderstood and they have been portrayed as something they’re not. There are over four hundred species of sharks in the ocean and sharks are considered the most dangerous animals in the ocean.

Lionfish were most likely introduced through the pet trade like the python. Although there is another theory that they were introduced by floating lionfish nest, it is rather unlikely considering that the nearest native range for them is the South pacific and the Indian Ocean around Australia and India. Lionfish were first reported off of Florida 's Atlantic Coast near Dania Beach in 1985. The lionfish 's habitat ranges greatly from 1 foot of water to 300 feet. It usually thrives in reefs but it is also easily found in hard bottom areas, mangroves, seagrass flats, and shipwrecks.

Then the people released the Burmese python as pets in to the wild of their growth rate. It became a threat to the Florida everglades. Once these python roamed the everglades they destroyed everything. This is why people of the everglades are in so much danger. However, in the meantime of the people letting these pythons a loss in the wild it has become a danger to the ecosystem.
