They have been known to feed on fish, dolphins, whales and seals. Sharks prefer meals with a high fat content to give them energy. They are ambush hunters, taking their prey by surprise from underneath. They have been known to come up from the bottom so fast that their entire body has left the water. The Great White has only one natural predator, the orca.
The pots were about 3 feet 6 inches and contained two to three dozen good size crayfish weighing about two several pounds. The men said it was about one hundred and fifteen to three hundred feet long. Another eyewitness saw a great white shark the size of a tractor trailer had attacked a person. Many sharks have been clocked out as fast as 1.5 miles and the mega shark could probably swim in a longer distance since this is a bigger shark. Two percent of the ocean has been overlooked by people ant it leaves ninety-eight percent of the ocean for the megladon can swim.
SO what the killer whale does it dives in the water and become submerged in the water for more than 15 minutes so they can use echolocation and listen where their prey is 3. Another selective pressure is the pressure that increases as they dive. Unlike human scuba divers, a whale doesn’t breathe air under pressure. It inhales only at the surface. Furthermore, in diving mammals, the alveoli collapse at about 3 atmospheres of pressure (about 90 feet), forcing air into the bronchioles (rigid air passages), a region where gases are not exchanged.
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.
Dr Euan Ritchie stated “When sharks were culled in Hawaii there was no long-term benefit because sharks attacks occurred immediately after”. Why then, waste billions of taxpayers’ money on a solution that has previously shown it does not work? In South Africa, again, according to statistics from the KwaZulu-Natal Shark Board, “less than 18 per cent of marine life caught on drum lines in South Africa in the 2011 to 2012 financial year have been great white or tiger sharks” with animals mentioned in the above paragraph contributing to the other 78%. A large scale cull would be highly redundant then as Australia would be no different from Hawaii and South Africa. In New South Wales and Queensland “there have been severe shark attacks on beaches that are protected by nets”, highlighting how wrongly this issue is being
It is uncertain how the lionfish arrived. Tests have suggested that only a few lionfish might have entered the Florida waters in 1992 when Hurricane Andrew swept through or they might have been released by an aquarium. Whatever the case, those few lionfish have multiplied rapidly; the
One such biological species which is going extinct is the angel shark. The Angel sharks are flat-bodied sharks, very ray-like, with broad pectoral fins that bury themselves in the sand or mud with only the eyes and part of the top of the body exposed. They have a blunt snout
• 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.
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.
According to FEMA reports, in September 26, 2005, they have already approved 265,000 applications for temporary housing payments. Eventually, many families will resettle back into their homes or even join in new communities, but regardless, families and communities have been dramatically transformed by the storm. Additionally, Hurricane Katrina has made one of the poorest areas in the United States even poorer. According to geographical analysis by the Federal Emergency Management Agency (FEMA) flood and damage assessments and year 2000 Census data, The CRS estimates that of the people to have been displaced by the hurricane, about half lived in New Orleans. Due to the city’s social composition, the storm most heavily impacted the poor and African Americans, who were less likely to have connected to the workforce and were educationally disadvantaged.
