Sharks tend to live between 20 and 30 years, but the number and diversity of shark species makes it difficult to give a definitive answer on sharks as a whole. Notably, Spiny Dogfish and Whale Sharks can live to be over 100 years old.
The bull shark life cycle starts when a mother gives birth to anywhere between one and 13 babies per litter. Its gestation period lasts 10 to 11 months, according to Wildscreen Arkive, and they generally give birth between late spring and early summer. They live in estuaries, river mouths and someti
A great white shark, or Carcharodon carcharias, is a large shark that inhabits the coastal waters of all oceans. It is the largest macro-predatory fish on Earth.
An adult great white shark reaches an average of 15 feet in length. However, several great whites exceeding 20 feet and 5,000 pounds have been recorded, making the species the largest predatory fish on the planet.
According to the Ocean Portal of the Smithsonian National Museum of Natural History, the average female great white shark is 15 to 16 feet long while the average male is 11 to 13 feet long. Very large great white sharks have been found at 20 feet long.
Whale sharks breed by internal insemination of a female by a male. The young are born alive and take about 30 years to reach sexual maturity. Whale sharks are believed to live 70 to 100 years.
Great white sharks live in temperate water around the world. They swim in shallow water as well as deep water.
Great white sharks have a lifespan of 30 to over 100 years. At the very beginning, two to 12 baby sharks, or pups, grow inside their mother for a full year before she gives birth. Great whites can be found in all major oceans and are well known for their large size. Some reach lengths of over 20 fee
In 2010, Barbara Block of Stanford University estimated the world population of great white sharks at less than 3,500 individuals. A June 2014 report from the Florida Program for Shark Research estimated that there are 3,000 great whites in the eastern North Pacific alone, suggesting a higher world
Great white sharks move by swimming. These powerful predators attain top speeds of over 15 MPH, but are only able to sustain such speeds for brief bursts. Great whites swim constantly because they rely on a breathing technique called ram ventilation. They swim with their mouths slightly open to forc
