Florida manatee, Trichechus manatus latirostris, a subspecies of the West Indian manatee, endangered. A mother manatee navigates with twin female calves in the warm springs on a cold winter day. Twins are rare and these are not documented but evidence suggests they are twins and not a calf plus an adoptee. Fish, bream, Lepomis spp. are following the manatees. Rare series. Horizontal orientation with blue water and reflection. Three Sisters Springs, Crystal River National Wildlife Refuge, Kings Bay, Crystal River, Citrus County, Florida USA.
