Abstract in brief

  • The study reveals that Neotropical crocodiles, which live in a wide range of coastal and inland environments, show significant genetic diversity and may actually consist of multiple separate species rather than one.
  • Researchers found clear genetic and morphological differences among populations of C. acutus, C. moreletii, and C. rhombifer, suggesting that what was once thought to be a single species is actually a complex of several cryptic species.
  • The work highlights evidence for rapid recent evolution in these crocodile populations across the Neotropics, supported by ecological, morphological, and genetic data from key island populations like Banco Chinchorro and Cozumel.]
