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.
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.
In a type three survivorship curve, a very large portion of the cohort is killed within the first few weeks of life (Natural Mortality Lab). C. Chyros and S. hispidus are economically important species as a food source. C. chrysos serves as a source of bait for other fishes. Both the blue runner and planehead file fish species eat plankton and associated matter (Rooker et al.
They have no natural enemies except man and power boats which are responsible for most manatee deaths- (in 1990, 218 manatees or 12 % of the total population were killed by boats), though the red tide (toxins released from the bloom of dinoflagellates) of 1982 and1996 killed over 15% of the population. It is suspected that environmental pollutions create disease vulnerability in marine mammals with manatees being no exception. An example is when 10,000 seals died in 1988 in Denmark and Sweden from viruses related to canine distemper. High concentrations of PCB’s were detected in necropsies of these seals, presumably from the water and fish they ate. Other threats include accidental
Zach Torres Oceanography T/TH 11-15-10 Great White Shark For many years there has been one animal that has struck fear in everyone that goes into the ocean. That animal is the Great White Shark. It has been known to exceed 20 feet in length, although most are about 5 meters long and weigh somewhere between 4000 and 5000 pounds. They live in almost all coastal areas that have a water temperature that stay between about 50 and 75 degrees. Perhaps the most well known place to see great whites is Dyer Island, which is off the coast of South Africa.
I’d also been there two hours too late. The best time to be there, Rick told me, was about two hours earlier than when I had arrived. Despite these uneventful beginnings, the Olympic National Park has proved to be one of the best – and most underrated – destinations I’ve ever had the honour of fishing in. Map of the Olympic National Park Olympic National Park — An Introduction Fast Facts * 12 major watersheds and more than 4,000 miles of rivers and streams. * 600 high lakes, two large lakes and more than 70 miles of intertidal habitats along the Pacific Coast.
FRANCES WALDEN CONSERVATION BIOLOGY WRITE UP OF ENDANGERED SPECIES DECEMBER 6TH, 2007 THE ANGEL SHARK (Squatina squatina). In the past few decades, the interest by many in protecting and preserving the world’s biodiversity have increased. Human activities, around the globe, possess a threat to biological communities. It has been proposed that many biological species will go extinct in the coming decades (Richard Primack, 2004). One such biological species which is going extinct is the angel shark.
Invasive Species of Florida Rachel M. Przybysz EVS 1001 Fassinger Wed. 6-10p 02/01/14 Invasive Species of Florida There are many species in the state of Florida which would be considered “invasive”, meaning they are not native, but somehow have adapted to this environment. The species which has caught the attention of many is the Nile monitor. The Nile monitor is a lizard native to the deserts of Africa, although they do thrive around the river banks. They are known to be the largest lizard with their lengths grown to a maximum of 7 feet 11 inches. The average length for an adult male is 5 feet 1 inch, and an adult female is 4 feet 5 inches.
It is, among hammerheads, the largest type. The great hammerhead shark is arguably one of the most fascinating species for various reasons. The great hammerhead is a shark, so it lives throughout the world’s oceans. They are found close inshore, as well as offshore in depths of between one and three hundred meters. More commonly, however, they are found close to shore.
This kind of brutal treatment of sharks is being tolerated all over the world and with 90% of the large shark population already wiped out, sharks are being depleted faster then they can reproduce. This puts a severe threat on marine ecosystems worldwide. Sharks play a vital role in the ecosystem, they have shaped marine life for 400 million years and are essential to the health of the planet, and ultimately to the survival of mankind. Sharks are known as apex predators, With fewer sharks around the species they prey on, such as cow nose rays have increased in numbers and in turn masses of cow nose rays are wiping out the bay scallops. This then has a large impact on the economy of local communities who rely on these scallops for a steady income.
