Sharks

Female Blue whales are generally larger than the males, but on average Blue whales can grow between 80 to 108 feet long and can weigh up to 120 tonnes. Newborn calves are approximately 22ft long and around 6 tonnes at birth. Exact measurements are difficult to calculate due to their extreme size.

Sharks do not tend to mind these parasites sticking to them all the time, remoras just stick to sharks to either get around or to eat the dirt off them. Remoras are streamlined so that it will not affect the shark's swimming.

Blacktip sharks are found in tropical and subtropical coastal, shelf, and island waters in the Atlantic, where they migrate seasonally between Brazil and Nova Scotia; the Gulf of Mexico and the Caribbean Sea, throughout the Mediterranean, and along the central West coast of Africa. In the Pacific they range from Southern California to Peru, including the Sea of Cortez , the Galapagos Islands , Hawaii, Tahiti , and other South Pacific Islands , to the northern coast of Australia. In the Indian Ocean they range from South Africa and Madagascar up to the Red Sea , the Persian Gulf , throughout India's coasts, and east to the coast of China.

Blacktip sharks can be found in both inshore and offshore waters, but they tend to stay close to the coasts at depths of 30 m or less. They are often seen near river mouths, bays, and mangroves , although they do not penetrate far into freshwater like bull sharks.

Killer whales are not considered dangerous to humans and do not prey on humans. There are accounts of killer whales turning on their keepers in Sea-world etc but these 'attacks' are extremely rare and the killer whale's in these instances did not attack the humans for food, more likely the attacks were due to frustration at being kept in captivity. Killer whales are quite capable of attacking and killing humans but choose not to, we are simply not on the menu. Sharks on the other hand are less fussy about which animals they prey on and if the shark is big enough and of the predatory variety then humans can be very much on the menu. Great whites, Bull sharks, Tiger sharks and Mako sharks kill between 3 and 4 people every year. When you compare this number to crocodiles who kill around 3000 people a year or tigers who kill hundreds of people a year it is quite clear that sharks have an undeserved reputation and the movie Jaws has a great deal to do with this.

Bull Sharks migrate into the fresh water rivers and channels to give birth. Giving birth in fresh water prevents other sharks from eating their young. Bulls are one of the only sharks that can live in either salt or fresh water, giving them the ability to migrate into the fresh waters leaving the threat from other sharks behind

The Great White Shark, also known simply as the "White Shark", or "White Death", has four main fins altogether. The three most obvious are, the two pectoral fins on the sides, and the large dorsal fin on the back. The smaller harder to see second dorsal fin is lower down the back. Here starts the debate about the number of fins. Many people refer to the tail as the "tail". If the tail is referred to as a fin then the name of the fin is "caudal fin", and there are several other small fins that the average person is not aware of and has never really seen. They are the pelvic, and the anal fin. Lastly, there is the tiny fin spine, which is very hard to see. If you count all of these including the "tail" as fins, there is a total of eight all together. This is a highly adapted species and listed as "vulnerable" with the "population trend unknown" by the IUCN Red List. For more details, please see sites listed below.

Manta rays, as well as sharks, are members of a group of fish called elasmobronchs. This means that their entire skeleton is made of cartilage. Elasmobranchs are vertebrates (have a backbone -- made of cartilage).

Manta Rays lack a stinger in their tale, therefore they do not sting.

but from stories I've heard they can bite.

Yes. Great White sharks prey upon fish (like Tuna, Rays etc), other smaller species of Sharks, dolphins, porpoises, seals, sea lions, sea turtles, sea otters and even sea birds. They prefer prey that has a high content of energy rich fat. They usually hunt early in the morning before the sun rises fully, when the visibility is poor

well sharks are not very smart, they have bad eye site but have the best sense of smell than all fish. example: you cut your foot on a sharp rock, its starts bleeding a shark may smell it 10000 miles away in the ocean. when sharks eat us or bite us they don't mean to, they possibly think your a seal because sharks think our blood tastes very bad when the swallow it they throw it up again. they think your a seal because your flopping your legs and arms everywhere so sharks are not that smart

From what i have just read yes meglodons are extinct. There is also alot of speculation about when they went extinct some think 10000 years ago others reckon alot longer. Either way how cool would it be to find a group of them they are awesome...............

No. Whale sharks are filter feeders. They eat tiny, tiny things they sift out from the water. They don't have the teeth or the throat to swallow anything like an anywhere near adult swordfish.

Yes, a shark does lay eggs, you can find them on the beach> they look a bit like a big runner bean but white and if they have baby's inside you can some times see them inside.

Near unlimited. It regrows teeth as it loses them.

THE GREAT WHITE HAS 24-26 POSITION IN THE TOP JAW AND 22-24 POSITION IN LOWER JAW MAKING 48-50 DIFFERENT TEETH POSITION EACH TOOTH ARRAGED IN ROWS OF 5-7 TEETH LIKE A CONVEYER BELT WHEN A TOOTH FALLS OUT THE TOOTH FROM THE FRONT THE TOOTH FROM THE NEXT ROW MOVES UP TO TAKE ITS PLACE AT ANY TIME A WHITE SHARK WILL HAVE ABOUT 300 TEETH IN VARIOUS STAGES OF DEVELOPMENT WITHIN ITS JAWS

The U.S. navy was named the Great White Fleet that completed a trip through parts of the globe from December 1907 to February 1909. President Roosevelt sent sixteen battleships along with escorts to demonstrate the U.S.'s eminent military and the exceedingly powerful navy adequacy. Through the fleet, Theodore Roosevelt sought to protect their overseas aquisitions and enforce treaties

Near Cape Town there is a fishing village called Gansbaai which is called Shark Alley which is known for the large quantities of great whites. And at the mouth of Kosi bay is a lot of bull sharks.

Gray dorsal side, white ventral (belly) side. Thick, pointy nose

A killer whale, electric eel, pods of dolphins and also sharks are cannibals which means the eat each other. But it depends on which shark and their size like the great white's size is massive and others that are smaller like the port jackson shark. Hope that helped. ;)

Some say you should lie still like a rock, because sharks may pay more attention to moving things than non-moving things.

Others say that there was a wildlife documentary about a guy who was underwater surrounded by great white sharks without protection. He attracted them by curling himself into a ball, and then he scared them off when they got close by quickly opening himself up.

They are the only shark with a snout and there only 5-3 Goblin Sharks left in the world there also rare and legendary and live 5,000 feet deep in the water very rarely to come up from the deep water also rarely seen

If you have ever seen jaws then sharks have a tendency to ram into the glass. The aquarium glass is not strong enough to hold a shark that size. Plus it could be dangerous 2 the people working there. If anything they are taken into a special facility and worked on' but not an aquarium.

The size of a baby shark depends on what kind of baby shark you are talking about. The size of a baby great white shark is five feet.

Yes they eat seals and that is what we are mistaken for when we get bitten
