Tigers

Short answer: Tigers (Panthera tigris) have stripe patterns unique to each animal, so researchers can identify individuals from photographs. Camera-trap surveys use this to estimate how many tigers live in an area and to track them over time, which is central to conservation.

The stripes, which run onto the skin, are thought to help break up the cat's outline in tall grass and forest. The footage shows tigers in the wild, with the presenter.
