Daily Existence of Manatees: Swim, Feed, Rest, Repeat, Captured in Brief
Florida's West Indian manatees, known for their gentle and curious nature, have been a significant part of the state's ecosystem for millions of years. These aquatic giants, also known as sea cows, have been living in Florida for approximately 45 million years and have been in their current form for over a million years[4].
These herbivores, which belong to the order Sirenia, are protected under federal and state laws in the United States. It is illegal to harass, hunt, capture, or kill them, with violations resulting in civil or criminal convictions, monetary fines, and imprisonment[1]. The Florida Manatee Sanctuary Act of 1978 further provides additional protection for manatees, declaring the entire state a refuge for these marine mammals[2].
The Save the Manatee Club offers opportunities for individuals to adopt a manatee or donate to support conservation efforts[5]. Thanks to these measures, the manatee population has seen a remarkable recovery, growing from about 1,267 individuals in 1991 to estimates of between 8,350 and 11,730 by 2025, representing a 400% increase and allowing the species to be reclassified from endangered to threatened in 2017[1][2][4].
However, despite these advancements, the West Indian manatee still faces significant threats. Boat strikes, caused by collisions with watercraft, remain one of the leading causes of manatee injury and mortality[1]. Boaters are urged to be cautious in areas where manatees are common and to obey all posted speed signs[6].
Habitat loss and degradation due to increasing coastal development and declining water quality also pose risks. Climate change, human disturbances, and increased mortality rates have further exacerbated these issues[1][2]. In recent years, manatee deaths have spiked, with 1,100 deaths recorded in 2021[2][4].
Experts warn that continued vigilance is crucial, as the increasing human population and development pressures in Florida, coupled with environmental changes, may necessitate a reconsideration of the conservation status of the West Indian manatee in the future[1][2].
In an effort to protect these gentle creatures, conservation plans include avoiding adverse impacts from in-water projects by following established effect determination protocols[3]. New research suggests that manatees have sensitive body hairs that help them detect changes in water movement, adding another layer of complexity to their protection[7].
Manatees are not territorial and can be found in large groups in warm water springs. There are three species of manatees: Amazonian, West African, and West Indian[3]. Despite their roly-poly appearance, these creatures are incredibly efficient eaters, with an adult manatee able to consume a tenth of its own weight in 24 hours[8].
In conclusion, Florida's West Indian manatee population benefits from strong legal protections and conservation programs that have enabled significant recovery. However, ongoing threats—especially from boat collisions, habitat degradation, and environmental changes—require sustained efforts to ensure their continued survival and growth. The public is encouraged to report injured, lone, or cold-stressed manatees to the Florida Fish and Wildlife Conservation Commission (FWC)[6].
