Lion vs Tiger

Lions and tigers are the two biggest cats in the world, and they are closely related big cats. At a glance both are large, muscular and tawny to orange, which is why photos and zoo signs cause arguments. The easiest differences are visible: stripes, a mane and where the animal is standing.

Behavior and range separate them too. Lions are social, living in prides built around related females, and they favor open grassland. Tigers are mostly solitary forest cats that readily swim. Size depends on subspecies, with large Amur tigers often topping lions, so weight alone is a poor identifier.

When you are looking at which

Lion

• The cat has a plain tawny coat with no stripes on its body.
• An adult has a thick mane around the head and neck.
• You see several cats together, including cubs, resting on open grassland.
• It is in sub-Saharan Africa, or the Gir forest of India.

Tiger

• The coat is orange with bold dark stripes along the body.
• The head and neck are bare, with no mane at any age.
• A single large cat walks alone through forest or swamp.
• It is swimming or lying in water to cool off, in Asia.

How this works

This page compares the two cats on traits that zoo and encyclopedia sources agree on: coat, mane, group behavior, habitat and measured weights. The quiz asks five questions about what you can see in a photo, video or enclosure, and each answer comes with a short reason.

Light, age and photo angle can fool you. Lion cubs have spots, lionesses have no mane, and some zoo cats are hybrids, which this guide does not try to identify. Use more than one cue, and treat a tie as a reason to look again.
