Social Learning and Cultural Transmission in Cetacean Pods
Quick fact
Some killer whale pods have vocal dialects so distinct that they are passed down from mothers to calves, and these dialects can become so different that they act as a barrier to interbreeding, effectively creating separate cultures within the same species.
Why this is interesting
Imagine a baby dolphin learning to hunt not by instinct, but by watching its mother use a sponge to protect its nose—a skill that has been passed down for generations. How do whales and dolphins develop such unique traditions?
