The high body fat content of dolphins helps them to stay warm in the cold waters they inhabit. It also provides them with energy reserves that they can use during long dives or migrations. Additionally, the body fat of dolphins helps to protect their organs from the impact of underwater pressure.
The amount of body fat a dolphin has can also vary depending on its lifestyle. For example, dolphins that live in warmer waters tend to have less body fat than those that live in colder waters. Similarly, dolphins that are more active tend to have less body fat than those that are less active.
Overall, the body fat content of a dolphin is an important factor that helps them to survive in their environment and perform the activities they need to survive.
