How long can a whale survive without food?

The ability of whales to survive without food can depend on several factors, including the species of whale and its body size. Some larger whale species, such as the sperm whale, may be able to survive for longer periods without food due to their large energy reserves. The time a whale can survive without food can vary, but some estimates suggest that larger whales may be able to endure up to several months or even over a year. These estimates, however, can vary based on factors such as the whale's overall health, metabolism, and environmental conditions. In cases of extreme food scarcity or environmental stress, the survival time may be significantly shorter.
