Why Killer Whales Migrate (It's Not Why You Think)

The video explores various reasons for whale migration, including food availability, warmer waters for birthing, and a new hypothesis suggesting skin care as a reason. A study on killer whales shows they migrate to warmer waters not for birthing but possibly to shed algae buildup. This skin care hypothesis might apply to other whale species, though more research is needed. The video concludes that while skin care could be a reason, other factors like predation also play a role.
