What are the primary differences between African and Asian elephants in terms of physical characteristics and behavior?

African elephants (Loxodonta africana) are generally larger, with larger ears shaped like Africa and two distinct species, the forest and savanna elephants. Asian elephants (Elephas maximus) are smaller, with smaller, rounded ears shaped like India, and have a more humped back. Behaviorally, African elephants are more social, often forming larger herds, while Asian elephants tend to live in smaller family units.
