What is the relationship between temperature and orca survival?

Orcas, also known as killer whales, are highly adapted marine mammals that are affected by changes in temperature in their oceanic habitats.

Temperature can directly impact orcas' survival in various ways. For example, warmer water temperatures can affect the availability and distribution of their prey, such as fish and marine mammals, which can influence their ability to find food and overall health. Warmer waters can also increase the presence of harmful algal blooms or toxins, which can affect the orcas and their prey.

On the other hand, colder water temperatures can also have an impact on orcas' survival. Extremely cold waters can lead to hypothermia and affect their ability to regulate their body temperature. Additionally, colder temperatures can lead to changes in the distribution and abundance of their prey, making it harder for orcas to find food.

Overall, the relationship between temperature and orca survival is complex and can vary depending on specific environmental conditions and other factors. It is important to study and understand how changing temperatures in the oceans can affect orcas and their ecosystems to help better protect and conserve these iconic marine mammals.
