Ecology and Evolution, Volume 16, Issue 4, April 2026.We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;
