Ligers and Tigons
If a lion mates with a tiger, what do you get? Well according to wikipedia ..
The liger is a cross between a male lion and a female tiger. It is therefore a member of genus Panthera. It looks like a giant lion with diffused tiger stripes. Like tigers (and unlike lions), ligers like swimming.
A cross between a male tiger and a female lion is called a tigon.
Known ligers exist due to human influence, either by deliberate human intervention, or by humans putting lions and tigers in enclosed spaces together. In natural conditions tigers and lions generally do not inhabit the same territory - the two species coexist in the wild today only in the Gir forest of India although their respective ranges used to intersect in Persia, China and perhaps also Beringia. Even where they do coexist, there have been no confirmed reports of interbreeding, though there are long-standing claims that this has happened.
