The Ghost Shark as it is called in South Africa, is found at a depth of 200m to more than 2.4km in temperate and tropical waters on the soft muddy bottoms of the ocean bed of the Atlantic and Pacific Oceans. Most species occur near continental landmasses or off oceanic islands and on the slopes of seamounts and underwater ridges.

i wanted to know the same thing but then when i researched it there hasnt ever been one in maine usa

Sand sharks, also known as sand tigers and gray nurse sharks, have a deceivingly ferocious look. They are large-bodied and display a mouthful of sharp teeth that protrude in all directions, even when the mouth is shut. Despite this, they are a docile, non-aggressive species, known to attack humans only when bothered first. Sand sharks are brownish-gray with rust-colored spots on top and white underneath. They have a flattened, cone-shaped snout and a distinctive, oblong tail with a notched, upper lobe that is significantly longer than the lobe below. Individuals range in size from 6.5 to 10.5 feet (2 to 3.2 meters) in length. Their name comes from their tendency toward shoreline habitats, and they are often seen trolling the ocean floor in the surf zone, very close to shore. They are found in warm or temperate waters throughout the world's oceans, except the eastern Pacific. Sand tigers are the only shark known to come to the surface and gulp air. They store the air in their stomachs, which allows them to float motionless in the water, seeking prey. They are voracious predators, feeding at night and generally staying close to the bottom. Their staple is small fish, but they will eat crustaceans and squid as well. They occasionally hunt in groups, and have even been known to attack full fishing nets. Although this species is widespread and is not widely fished for food, it has one of the lowest reproduction rates of all sharks and is susceptible to even minimal population pressure. For this reason, it is listed as vulnerable and is protected in much of its range. They are not known to have sufficient predators other than other sharks, and so the answer is really, other shark species.

There are very mixed reviews with this product. It has a huge amount of people that rate it 5 star, but on the contrary, a lot of people gave it 1 star. Many said they just got lucky the first time they used it and will never use it again as it is unreliable.

since right after a sharks came into being

They mistake shiny human skin on arms and legs for fish, and it's in the sharks nature to "nibble" on something to see if the object is edible. The "nibble" however can vary depending on the size of the shark and its jaws. Also, when sharks smell blood, it causes them to frenzy which causes the sharks to become more aggressive and lose their sense of discrimination towards humans as food.

Zero. They have been extinct for several million years.

Animals swim because they have these special structure, and this are the fins and tails, but they cannot swim if they cannot breath under water and this is called gills.

It really depends on the type of animal you are talking about. If you are takling about a shark or fish. Then, see above. If you are talking about an animal such as a hippopotums then they simply do what we humans call a 'Doggie paddle' they use their legs to basically 'Walk' through the water.

Skates look similar to sting rays. They are flattened cartilagenous fish, and have tails. Their bodies look like a flattened disk or plate. Generally skates have a pointed front/nose where rays have a rounded front. They are closely related to rays.

The whale is also a mammal, just like the tiger. The shark is a fish. The reproduction in the mammals happens through pregnancy while in the fish they have "eggs", the conception is out of the body, their breathing system is quite different and so is the digestive tube. Anyways, the differences are many, the main thing you should check is: how is a mammal different from a fish?

As of this year, there are over 28,000 species of fish. However, new species of fish are being discovered every year and this number is constantly increasing.

because they think they may be a threat. also in some countries they eat shark soup.

the white shark is perhaps the most notorious of all sharks with undeserved reputation as a man eater and threat to humans.

this shark can attack swimmers and boats without provocation.

There has been 6 recorded Blue Fin Shark attacks off the coast of Nice in the French Riviera. The last recorded attack by a Blue Fin Shark in Nice was in July 2010. An 18 year old girl called Sheenagh was attacked by a Blue Fin while out for a brisk swim on a warm July morning. Her swim was cut short when she felt a tug on her left arm and looked down to find a Shark hanging off her arm. She managed to punch the shark in its nose and started to swim towards the shore, the shark chases after her for what some might call 'revenge' an managed to bite her leg. Luckily for Sheenagh a near by swimmer by the name Katie was able to hit the shark so it let loose of Sheenagh so she could swim to shore with Sheenagh on her back. When they arrived on shore Sheenagh was slipping in and out of consciousness, Katie performed CPR as she had recently been awarded her first aid certificate and was top of her class, until the ambulance arrived. Sheenagh sustained moderate injures, but if it wasn't for Katie she probably would of been taken to the Blue Fin Shark lair and eaten by the Sharks for the sunday night roast and never would of been heard from again. Sheenagh has made a full recovery, however is now missing her left arm, and her her fingers from her right hand had to be place onto her right foot as the shark ripped of her toes. To this day though Sheenagh is yet to re enter into the ocean which was almost her watery grave. We wish Sheenagh to over come her fear and maybe one day soon we will be able to see her swimming in the ocean again.

No but a cell membrane goes over white when it bites it's prey to protect it from a counter strike.

The only enemies they have are other sharks.

All species on Planet Earth including sharks should consider Humans their enemy we are poisoning the planet and destroying there habitat at an alarming rate.

Do you mean what is the body temperature of a g+Great White Shark, or what climate temperature do they prefer to live in?

It's body temperature I believe is around 15°C.

They seem to prefer waters with a temperature of 15-22°C although the range in which it has been recorded varies from 4-27°C.

White sharks can be found in most temperate zones, but are rare in tropical seas. In eastern North America, they can be found as far north as Newfoundland in summer, and as far south as Cuba.

On the west coast, they are found from Washington to Mexico.

they dont, when the mother white shark delivers the pups (usually 2 to 10 at a time)she swims away and the pups are on their own. Newborn pups are about 4' - 5' (122 - 152 cm) long and will grow about 10" (25 cm) a year to maturity.

They are known to be the oldest animal ever

( Hi Ben Marmoll)

They have very good smelling senses, and are one of a kind usually.

Yes, There are sharks in Argentina but they are called Seuati
