How large do great white shark grow?
How big can sharks grow?
Sharks come in a range of sizes. The largest shark known is the whale shark, which reaches lengths of 12 metres (almost 40 feet) or more. The smallest shark, the dwarf shark, is only 25 cm (10 inches) long. The basking shark is the largest shark in Atlantic Canada, routinely reaching lengths of 8-9 metres. The largest confirmed great white shark caught in Canada was more than 5 metres long. It was caught off of PEI in 1983. Before this, a white shark was caught in a herring weir in the Bay of Fundy in 1930 which was reported by local fishermen as being 11 metres long. For awhile, this was considered the largest specimen ever caught, but when the jaws were compared to that of other jaw specimens, they were more similar to a shark of around 4.8 metres. The world record is 6.3m.
Consider the dynamic of shark mating. female great whites are more often seen with the back of their pilot and dorsal fins torn and cut. it is believed to come from the male shark biting hold during mating. this would mean the male shark is around 30% smaller to mate successfully. male specimens on very rare occasion have been caught in the 17 to 18 feet region. by this method, it would indicate females out there of the 25 to 26 feet range.
The biggest great white shark?
The biggest Great White ever caught was a female of 6.4 meters (21ft), which was caught off Cuba in 1945. It weighed just over 7,000 lbs and its girth reached 4.5 meters (over 8feet); several lorries were needed to tow and transport it. A 10 meter specimen is also said to have been captured, but neither photo nor expert account exists, only subjective statements. The record specimen are always female, since in the sharks, females have larger measurements than males.
grey nurse and great white shark are indangerd because their fins
they are cut of and the sharks drown
What size tank do you need for a red tailed shark?
That depends on what kind of shark it is, but in general nothing less than 180-200 gallons. For some sharks, you need at least 700 gallons!
What kind of home does a great white shark have?
Sharks do not have homes like we do or other land animals. They roam free in the oceans of the world and have the whole sea to explore, hunt, and swim in. They do not require shelter.

What type of animal is the Manta ray?
Manta rays are the largest of the ray family. They are closely related to sharks, but these animals are harmless to people. They do not sting and are usually indifferent to divers.
The length of a shark's teeth depends on the type of shark. The largest living shark, a whale shark, has teeth that are relatively small, even tiny. The smallest living shark, the dogfish, also has tiny teeth, while the great white shark has teeth the size of about 36 mm, or 1.43 in. But the largest shark to have ever lived, the megalodon, could grow teeth longer than seven inches long.
sharks. i don't know much about the subject, so i can provide much.
What shark was bigger than a megaladon?
The name Megalodon comes from the Greek and means "big tooth". This name describes the large number and size of the fishes teeth. It is thought that the Megalodon had four different kinds of teeth, Anterior, Intermediate, Lateral and Posterior. Palaeontologists believe that its giant jaws would have contained around 250 teeth.
It was the apex predator of its time, this means that the adults were not preyed upon by other animals, as they were at the top of the food chain.
Fossil evidence suggests that the Megalodon would have fed upon many other animals, including early whales. It would have had a very large appetite due to its incredibly large size and would have needed to eat in large quantities in order to sustain itself.
The Megalodon was a pelagic fish and lived in all the oceans right around the world. It most likely lived in warm water regions, but as the oceans were a lot warmer during the ear that this shark was alive, its dependence on warm water would not have restricted its range. This idea is supported by the fossil records which indicate this species flourished all over the world.
As with all sharks, the Megalodon would have been an opportunistic predator. It may have also utilized an ambush technique while hunting in order to catch its prey. It is thought that the Megalodon would have attacked with a lot more power than that of a great white shark. It would have no qualms about focusing attacks on boner portions of its prey, a tactic that the great white shark usually avoids. The Megalodon would inflict as much damage as possible in the first attack and then circle around its prey waiting for it to weaken. This is the same method that a lot of carnivorous sharks use today.
There are multiple factors that contributied to Megaladon's extinction:
1. As the world got cooler, Megaladon's chief prey, whales, moved into the colder waters where the shark wouldn't survive for long.
2. Orcas (killer whales) developed, attacking Megaladon's prey as well as hunting the sharks themselves. A medalodon is a giant prehistoric extinct species of shark.
Do sharks have to mate with another shark to have a baby?
Baby sharks are called pups. Just like there are many types of sharks, there are also different ways that sharks come into this world. There are three ways that sharks are born:
eggs are laid (like birds)
eggs hatch inside the mother and then are born
pups sharks grow inside the mother (like humans)
Sharks can have from 1 to 100 babies at a time, depending on the type of shark. The ones with pups that grow inside the mother have fewer babies at a time than sharks that lay eggs outside the body.
Sharks do not care for their babies after they are born, but they do search for a safe place where they can lay their eggs or give birth.
What is the difference between a fin and flipper?

What is the scientific name for a smooth hammerhead shark?
The scientific name for a smooth hammerhead shark is Sphyrna zygaena. This species is known for its distinctive flattened head, which helps improve its sensory capabilities. Smooth hammerheads are found in warm waters and are often seen in schools. They are characterized by their elongated bodies and can grow up to 4.5 meters (15 feet) in length.
What would happen if sharks stop eating other fish?
In the sea sharks play a very important role. They don't just eat all fish, they eat for a good cause. Some sharks eat dead fish and if the population were to decline then we would have dead fish in the ocean.
What are the colors of a mako shark?
Type your answer here...
These sharks are a brilliant blue gray or cobalt blue on top, changing to light blue
along their sides and snowy white on their belly and lower jaw. Soon after death their brilliant color
fades to grayish brown. Shortfin mako sharks are large, streamline shaped fish that have a conical
snout and a crescent shaped tail fin. Shortfin makos, though similar to blue sharks in color, differ in
the shape of their snout.
Why do fishermen want dogfish sharks?
Dogfish sharks are a commercially viable species meaning a fisherman can make money selling the fish. Fishermen earn about .25cents per pound for "spinys".
The meat of a dogfish is used in several countries as a source of food. In the UK the meat is used as the fish in one of England's staples "Fish and Chips". The fins of the dogfish are used by the Chinese as a delicacy often served at weddings and other such occasions. The belly flaps of a dogfish are served in the Beer Gardens of Germany as "scherlocken", a pickled snack.
The dogfish has been over regulated by NMFS for years and the population has become massive. The dogfish are highly predatory (as most sharks) and swim in large schools. They eat everything in their path including juvenile cod,pollack and haddock. The over population of these sharks is obvious as anyone who spends anytime fishing in the North East US can tell you. If you fish 400 hooks looking for cod you will pull up 400 dogfish.
NMFS has recognized their mistake and have implemented plans for fisherman to take more of these sharks to supply the European market and to "thin the herd" here at home in order to give other species a fighting chance to grow. Hope this answered your question.
Im a commercial fisherman out of New York.
Why is the Manta Ray called Devil fish?
because it likes to eat PEOPLE :O
HELPPPPPPPPPPPPP!!
OMG!! it is known 2 b a sea monster just coz of how it looks! that's all!
I don't think it is safe to say that dolphins would always save humans from a shark attack. However, there ARE several accounts of humans, who were attacked or threatened by a shark, and were rescued by an onslaught of dolphins who attacked the shark.
