How long does the average shark live for?

Answer 1

'Shark' is the collective name for a type of fish, so there is no collective life span. However, here are the life spans of the more well known sharks

Great White- Unknown, however it is believed to be around 100 years

Tiger Shark- 11 years

Hammerhead Shark- 25 years

Nurse shark- 25 years

I do not know why the Great White life expectancy is so much higher than the others.

Answer 2

Great White Shark - Some people estimate it to be about 100 years, but this has not been proven.

Tiger shark - Perhaps 30 - 40 years.

Nurse shark - Life span is about 25 years (in captivity).

Spiny Dogfish shark - Estimated 25-100 years.

Whale shark - Estimated 100 - 150 years.

Many of the other shark's life spans are unknown.

Answer 3

This is harder to answer than it seems. Sharks are fish - and as most fish, they continue to grow through their lives. They do not die of old age, but due to disease, predators, starvation, injury etc. Outside of captivity, most types sharks have an unknown lifespan. In captivity they live much. much shorter lives (as much as only a quater).

The whale shark has been know to live to around 150 years, which is as good a guess as any.

Answer 4

Many shark lifespans are still widely unknown. Not many people realise that there is so much we actually don't know about our oceans. Much of it is theorised, like outer space.

• Great White Shark: Some research indicates they live up to 30 to 40 years. Some research suggests 70 years. Other research indicates they have roughly the same lifespan as a human. It is commonly-spread that they live up to 100 years, this has notbeen proven.
  
  

• Tiger Shark: About 27 years average, though some may live to 50.
  
  
• Nurse Shark: Unknown in the wild, but 25 years in captivity.
  
  
• Hammerhead sharks: About 20 to 30 years.
  
  
• Silky Sharks / Blackspot Sharks: About 25 years.
  
  
• Greenland Sharks: Unproven but suggested to be about 200 years. This is likely an exaggeration.
  
  
• Spiny Dogfish Shark: About 25 years up to a theorised 100 years.
  
  
• Sandbar Sharks / Brown Sharks: About 20 to 30 years.
  
  
• Whale Sharks: Theorised to be 100 to 150 years.

Answer 5

They can live up to 20-30 years old. A Whale Shark can live well over 100 years of age. Dogfish can live to be around 100 too.
