What animal takes care of its young the longest?

That's a tough one! It's difficult to definitively say which animal takes care of its young the longest, as it depends on how you define "takes care of" and what kind of care you're considering.

However, humans generally take care of their young the longest. Humans typically raise their children for many years, providing food, shelter, education, and emotional support, sometimes even into adulthood.

Other animals that are known for extended parental care include:

* Elephants: Mothers stay with their calves for several years, teaching them about social interactions and foraging.

* Wolves: Wolves raise their pups in a den for several months, teaching them hunting skills and pack dynamics.

* Birds of prey: Many birds of prey, like eagles and hawks, care for their young for several months, teaching them how to hunt and survive.

Ultimately, the answer depends on your specific criteria.
