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

Marine 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.

American manatees adjust their diet composition and trophic niche breadth across different coastal regions

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.
