When the pesticide is placed in a pond, it kills every fish in that pond. Fishers are told to kill any Northern Snakehead they find. Unlike other fish, they are highly capable of traveling on solid ground to new environments by simply wiggling their body around. (csa.com). The only predators the Northern Snakehead has in the United States are other Northern Snakeheads and humans.
The Brown Tree snake is a native snake to Australia, Papua New Guinea, and Melanesia. This snake is known to have a dark brown color and can grow up to 9 ft long a little above the average wild snake size. These snakes feed on birds, lizards, bats, small rodents, and occasionally other snakes. Due to the lack of natural predators in certain areas and an excessive amount of prey, the population of these snakes is bound to increase. They are commonly found in trees, caves, and the ground and near limestone cliffs.
The Oceanic White-Tipped Shark is a pelagic shark which means it lives close to the surface and rarely goes to the ocean floor. It is an aggressive slow moving fish that usually will find a carcass of a whale or other large marine animal and dominate the feeding frenzy. It gets its Name white-tipped shark because every fin on the shark has a white tip except the anal fin which has a black tip. They inhabit most of the Salt water of the world because they can live in cold or warm water. Excluding the occasional feeding frenzy, white tips also eat a diet that consists mostly of cephalopods.
The most dangerous species of jellyfish is the box jellyfish, which is widely known as the sea wasp as well. This type of jellyfish is the most poisonous animal in the world. The box jellyfish belongs to the class Cubozoa. Their tentacles are usually several feet long, and their body has a box-like shape to it and can be as small as a few millimeters in diameter to the size of a
Asian Carp Invasion David Long University of New England The United States Environmental Protection Agency recently began fighting an invasive fish called the Asian Carp. These fish are causing problems around the world destroying fishing industries and eco systems. There are four species of the fish, of the two the bighead and the silver carp are the closest to invading the great lakes. The bighead carp can grow up to one hundred pounds and the silver carp are known for jumping out of the water when frightened and scaring boaters. These fish pose a significant threat to the great lakes due to their large size and feeding habits.
When mating both male and female change color. The male’s eye band would turn to an almost black color and the white area around their mouth would darken. The female’s color would become bland in color. At dusk, the pair of emperor angelfish rush to the pelagic spawn where the fertilized eggs released will be taken away on the currents and drift out to the ocean. After releasing the eggs they rush back down and by quickly doing this egg eating predators may not see their release.
Predators eat animals they have killed. As an example, lobsters are predatory. Crabs, on the over hand, can be predators, herbivores or scavengers. They use their large claws to attack the prey. The crusher claws are used to
Sharks are known to be fierce predators of the sea, and with the capability to venture into freshwater it makes their hunting grounds very vast. While other sharks could have difficulty finding food at sea, the bull shark may roam into rivers
The Degradation of Coral Reefs There are numerous reports on coral reef degradation including the article I found called “Study finds Caribbean Corals in Dire Trouble”. Coral reefs, not only in the Caribbean, but world wide have been damaged losing their ecological resilience. Having seen Coral reefs while snorkeling in Hawaii, coral reefs are arguably the world’s most beautiful habitats. Coral reefs have been called the rainforest of the oceans because of their rich diversity of life they support. There are thousands of different species of plants and animals that use or live in the coral reefs.
Coral reefs are home to more than a quarter of all marine life and provide the foundation that many ecosystems need to survive. These reefs are known to be extremely fragile and slow-growing. But due to a number of threats, the world's coral is being harmed and destroyed at an alarming rate. When a reef is found unable to maintain an ecological balance, the effect fishing has on the reef can be detrimental. Humans have been known for destroying coral reefs through unlawful fishing habits.
