Description

West Indian manatees are tropical and subtropical aquatic mammals that can develop cold stress syndrome (CSS) when subjected to water temperatures below 20℃. This study investigates the potential impact that cold winter water temperatures in Florida may have on manatee body shape as a selective force to reduce surface-area-to-volume ratio (SA:Vol; i.e. Bergmann’s and Allen’s Rule). Morphometric measurements collected from state-mandated necropsies (1974-2014) were used to calculate surface area, volume, and mass. The SA:Vol, controlled by mass, is predicted to be significantly larger for manatees that died of CSS compared to manatees that died from other causes.
