West Indian manatees (Trichechus manatus) are separated into two allopatric subspecies: the Florida manatee (T. m. latirostris) and the Antillean manatee (T. m. manatus). In the winter of 2020–2021, an adult manatee was sighted off the coast of Cancun, Quintana Roo, Mexico, in areas where Antillean manatees are not typically seen. The individual had distinct watercraft scars on its body, which were matched using photo-identification to a known male Florida manatee (PE424) that had been repeatedly photographed in Florida since 1998. This is the first record of a Florida manatee visiting the Mexican Caribbean. Previous reports of individuals from this subspecies in Cuba, combined with genetic evidence, suggest some level of connectivity among geographically separated manatee populations.

西印度海牛 ( Trichechus manatus ) 分为两个异域亚种：佛罗里达海牛 ( T. m. latirostris ) 和安的列斯海牛 ( T. m. manatus )）。在 2020 年至 2021 年冬季，在墨西哥金塔纳罗奥州坎昆海岸附近，在通常看不到安的列斯海牛的地区，人们发现了一只成年海牛。该个体身上有明显的船只伤痕，通过照片识别与自 1998 年以来在佛罗里达州多次拍摄的已知雄性佛罗里达海牛 (PE424) 相匹配。这是佛罗里达海牛访问墨西哥加勒比海的第一条记录。先前关于古巴该亚种个体的报告，结合遗传证据，表明地理上分离的海牛种群之间存在某种程度的连通性。
