Lions are the only big cats that live in social groups called 'prides'.
Asian lions live in smaller prides, are smaller in size and have smaller manes than African lions.
Some male lions do not have manes, they are seen most often in East Africa.
Lions are the only members of the cat family to have males and females that look distinctly different.
Only lions have a tuft of dark hairs on the tips of their tails, which helps them communicate with other lions in their pride.
