Research overview: coat and stripe variation in tiger taxonomy

Tigers vary in ground color, stripe density, and body size across their range, and these traits were historically used to distinguish subspecies. This overview examines how reliable coat characters are for classification. It explains that while Sumatran tigers tend to be darker with denser stripes and Amur tigers paler with fewer, such patterns are clinal and overlapping, making single-trait diagnosis unreliable. The piece addresses color aberrations like white and golden tigers, which are individual recessive variants with no taxonomic significance, despite popular misconceptions. It connects to the broader lesson that coat pattern, though striking, is a weak basis for felid taxonomy and must be corroborated by independent evidence. Modern classification treats stripe and color variation as supplementary rather than defining characters.
