Blue whales can live for over 80 years. They are one of the longest-lived animals on Earth, along with other large whales such as humpback whales and bowhead whales. Blue whales reach sexual maturity at around 10 years of age and continue to reproduce and have calves throughout their lives.
What are the factors affecting lifespan of blue whales
There are several factors that can affect the lifespan of blue whales, including:
- Natural predators: Although blue whales have few natural predators due to their size, they can be attacked by orcas (killer whales) in some cases. Orcas are known to prey on young blue whales and have been observed attacking and killing adult blue whales as well.
- Human activities: Blue whales are endangered due to human activities such as commercial whaling, which has significantly reduced their population. Other human activities, such as shipping and ocean noise pollution, can also have negative impacts on blue whales and their ability to live long lives.
- Health and nutrition: Like all animals, the health and nutrition of blue whales can affect their lifespan. Poor health and malnutrition can lead to a shortened lifespan, while good health and a healthy diet can help blue whales live longer.
- Genetic factors: Some research suggests that genetics may also play a role in the lifespan of blue whales. Some individuals may have genetic traits that allow them to live longer than others.
