Sharks are some of the most remarkable creatures on Earth. With few visible signs of aging, they have been around since before dinosaurs, and a few species can even outlive us! From conception to death, sharks have an incredible life cycle that ensures their population continues to thrive.


Sharks reproduce through a process called ovoviviparity. This means that the young sharks develop in an egg inside the mother’s uterus, and hatch inside their mother before being born. Depending on the species of shark, the pregnant mother can be pregnant for between 5 to 12 months.


Once the baby sharks are born, they almost immediately need to start hunting for food by themselves. According to the species, this can mean either staying close to their mother to get her help and protection, or swimming to a part of the ocean away where they will meet more of their own kind.


Once the shark is fully grown and mature, it will be able to reproduce and start a family of its own. The age at which sharks reach maturity varies greatly, but is typically anywhere between 5-15 years.

Life Cycle

The average lifespan of a shark varies depending on the species and it can live anywhere from 20 to 100 years. The oldest recorded shark in history was a Greenland Shark that was estimated to be about 400 years old.

Adaptations and Threats

Sharks have evolved and adapted to their environment to survive over millions of years. However, with humans activity such as overfishing and pollution, many of the shark species face the threat of extinction. This is why it’s important that we do our part to protect sharks and their habitats to ensure their future survival.


Sharks have existed for hundreds of millions of years and hold a special place in the animal kingdom. Their life cycle is a testament to their tenacity and optimism, and it is up to us to ensure that they can continue to thrive.

Key Points:

    • Sharks reproduce through ovoviviparity and hatch inside their mother.
    • Maturity is reached between 5 and 15 years.
    • Their average life span varies between 20 to 100 years, with the oldest shark estimated at 400 years old.
    • Sharks are threatened by human activities such as overfishing and pollution.
    • We should work towards protecting sharks and their habitats.
