Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.
