Leopard Shark Patterns: Variation or Life Stage Indicators?

Two leopard sharks glide through the same coastal waters, yet their skin tells two different stories. One displays bold, dark bands; the other shows a pattern of faint, scattered spots. For researchers, the question is whether these differences are simple variation or reliable indicators of age. This distinction matters for field identification and population studies. The variation we observe is real, but it does not obscure a clearer biological signal.
