The Northern Snakehead can survive up to four days out of water and can grow up to 33 inches long. The species has been nicknamed “Frankenfish” due to its shark-like teeth and aggressiveness. It was first introduced in a pond in Crofton, Maryland in June 2002. Researchers believe the species ended up in the U.S. due to uncaring disposal of aquarium pets. Other researchers think some people were trying to breed Snakeheads as they bring a large amount of money in some areas.
Litter sizes vary from one to 15 with White Tips are a commercially important animal to humans seeing as how its fins are used for shark fin soup and its meat and oils utilized for consumption, its hides are often used for leather as well. Many scientists have referred to this shark as the most dangerous shark in the world, despite the more notorious Great White and Tiger, the white tip is responsible for more human deaths then all shark species combined. With one incident alone, the torpedoing of USS Indianapolis on 30 July 1945, giving a minimum figure of between 60 and 80 sailors killed by sharks. While diving with these sharks is done often it is not advised. So Respect and Fear this great animal who is number 4 on animal planets deadliest
Orcas in captivity face premature death, “In the wild they have an average life expectancy of 30 to 50 years—their estimated maximum lifespan is 60 to 70 years for males and 80 to over 100 for females. The median age of orcas in captivity is only 9, and orcas at SeaWorld rarely make it even to the average life expectancy of their wild cousins.”(SeaWorld oh Hurt) Orcas need to swim up to a hundred miles each day but in the parks they are only confined to a tiny pool and forced to swim in the same space their entire life. Being in such small spaces, light has been shed on the fighting between killer whales. “Orcas who are not compatible are forced to live in tight quarters together. The resulting anxiety and tension cause fights between orcas.
They can weigh up to 200 pounds and are native to jungles and grassy marshes. The Burmese is a highly carnivorous species; their diet consists of many different types of animals including mammals, birds, and reptiles of appropriate size to fit into their mouth. These pythons tend not to eat every day; they spend most of the day warming up from the sun, providing them with the necessary energy to hunt. Once food is obtained, depending on the size of the meal they will spend a few days to several weeks absorbing heat to digest there food. The Burmese was introduced by human mediated transport.
• The common garter snake feed on worms, fish, insects, amphibians, and uncommonly mice. • Aquatic Birds: Other than ducks and geese, over 20 species of aquatic birds can be found in the Rideau River. Many aquatic birds use the river as a “migratory staging area”. Ducks in the area eat similar to the common snapping turtle including plants, insects, and small amphibians. • Fish: The Rideau River has a variety of cool-water fish.
The Emperor Angelfish also known as the Imperator Angelfish is usually found in most parts of the Indo- Central Pacific Ocean and in the warmer parts of the Red Sea. They live in areas with rich coral growth Young emperor angelfishes tend to live alone, hiding in reef holes and crevices. In some parts young emperor angelfishes frequent shrimp cleaning stations and would occasionally help shrimps pick off parasites and dead skin from a fish waiting to be cleaned. The emperor angelfish is a carnivore unlike most species of angelfish that are herbivores. Emperor angelfish eats coral heads, small invertebrates like sponges, and crustaceans such as shrimp and shellfish.
The reason I don’t think that the consumption from predators is why the population is declining so rapidly is the fact that these predators have been hunting these fish for hundreds of years. It wasn’t until humans came into the picture that the population started to shrink. The predators now have to compete with us for their food. The magnitude of over-fishing is often overlooked and the rapid growth in demand for fish and fish products is leading to fish prices
They need to feed their chicks and the colonies are often a long way from the fishing grounds. Each chick needs about 42 kg of food from each parent.The entire breeding population of emperor penguins may consume as much as 1,500,000,000 kg (1,500,000 metric tons) of krill, 115,000,000 (115,000 metric tons) of fishes and 3,500,000 (3,500 metric tons) of squid each year. Method Of Collecting And Eating Food Penguins feed at sea. Most feeding occurs within 15.3 to 18.3 m (50-60 ft.) of the surface.
The world’s coral reefs covers only about 368,000 square miles occupying less than three tenths of one percent of the ocean’s floor. Although the ecosystem is a small one, close to one million species of fish, crabs, eels, molluscs, sponges, worms, algae, grasses and other marine life call the coral reefs their home. But the coral reefs are depleting. There are many factors that contribute to the depletion of coral reefs. They are coral mining, climate, diseases, tourism, blast fishing, farm runoff, sewage, oil and industrial pollution.
Scientific Whaling in the Southern Pacific Ocean, Effects on the Environment and Legislation. Introduction Whales have inhabited the earth’s oceans for millions of years and are a vital part of the ocean’s ecosystem. Since the 1600s, whales have been hunted out of the seas and no species has fully recovered. They also contend with pollution, climate change, ozone layer loss, overfishing, vessel traffic, noise and entanglement in fishing gear. Whales are mammals that live for a long time and breed slowly.
