Freshwater Baby Manatees and Big Manatees Freshwater River Dolphin
The Florida manatee, Florida'southward state marine mammal, is a large aquatic relative of the elephant.
Manatees are grayish brown in colour and have thick, wrinkled skin on which there is oftentimes a growth of algae. Their front flippers help them steer, or sometimes crawl, through shallow water. They also have powerful, flat tails that help propel them through the water.
Like other grazing animals, Florida manatees play an important role in influencing institute growth in the shallow rivers, bays, estuaries, canals and coastal waters they call home. Historically, manatees in Florida relied on natural springs to stay warm during cold weather.
Florida has the largest concentration of natural artesian springs in the world; unfortunately, many springs have been altered, degraded and even lost completely due to groundwater pumping for urban and agricultural development, drowned nether reservoirs, or blocked by dams. At the same time, we've built electric power plants and other structures that produce artificial sources of warm water, and many manatees (over 60% of the population) have learned to rely on these outflows to provide warm water habitat. Whether natural or man-made, manatees depend on warm waters to spend the coldest days of winter.
Defenders' Affect
In the late 1990s, Defenders was a atomic number 82 plaintiff in federal lawsuits against the U.S. Fish & Wild animals Service and the Florida Fish & Wildlife Conservation Commission claiming inadequate protections for Florida manatees. The consequence was a landmark settlement in 2000 that resulted in many additional protections for manatees.
Defenders advocates for protecting and restoring natural springs and conserving other of import marine and freshwater habitat for manatees. Defenders continues to advocate for manatee protection speed zones to reduce manatees' chances of being hitting by speeding boats and provides outreach and education about coexisting with manatees.
Nosotros continue to focus on improving protections for manatee habitats, such equally in Crystal River National Wild animals Refuge and other areas within Kings Bay. We are working with government agencies, power companies and other organizations to place and conserve regional warm water networks to assist transition manatees abroad from depending on artificial sources of warm water.
One central project is Defenders' advocacy and education piece of work to restore the Great Florida Riverway, a 217-mile system of three rivers and 50 springs that flows northward from key Florida to the Atlantic Bounding main via the St. Johns, Ocklawaha and Silver rivers. Restoring the natural flow of the dammed Ocklawaha River volition open up essential warm water habitat for many hundreds of manatees.
Threats
Manatees go along to face many threats, including collisions with boats, habitat loss and degradation, fishing gear entanglement, human harassment, exposure to red tide and other harmful algal blooms, and climate change. The greatest long-term threat is the loss of warm h2o habitat.
Habitat loss, cold stress and starvation caused past pollution-fueled loss of body of water grasses (a major food source) take culminated in a large-scale, ongoing manatee die-off in 2021. With over 700 animals lost every bit of Apr 30, 2021, this is a crisis for manatees that the National Oceanic and Atmospheric Assistants (NOAA) alleged an Unusual Mortality Event (UME) forth Florida's Atlantic coast from the Indian River Lagoon to the Keys. Surpassing 2013, which saw 830 manatee deaths in total, 2021 is on track to exist the deadliest twelvemonth on tape for manatees. Defenders is urging leaders to accost the root causes of this UME: manatee habitat loss and systemic mismanagement of Florida'south state and h2o.
Protection Status

What Y'all Can Practise
Support programs for land and water acquisition and restoration. Manatees are sensitive to human harassment and may get out their vitally important warm-water areas as a result. Obey viewing guidelines and never feed, water or harass manatees by interacting with or touching them. Obey canoeing speed limits and no-wake zones and picket out for manatees while boating. Report manatee deaths, injuries, harassment, accidents or orphaned manatees to the Florida Fish and Wildlife Conservation Commission's Wild fauna Alert number: 1-888-404-3922.

Facts
Trichechus manatus latirostris
10 -12 feet long and one,500 – one,800 pounds
Range/Habitat
Manatees are found in the warm waters of shallow rivers, bays, estuaries and coastal waters. Manatees cannot tolerate waters beneath 68° F for extended periods, since cold water tin can stun and fifty-fifty kill them. Manatees take up residence primarily in Florida'due south coastal waters during winter. They disperse in summertime, with more and more than manatees spending fourth dimension in other southeastern states; some individuals accept migrated equally far north every bit Massachusetts and as far west as Texas in summer.
Population
Today's population estimate is effectually viii,800 animals.
Reproduction
Calves are built-in weighing betwixt lx and seventy pounds and measuring about iii-four feet long. They nurse underwater.
Mating season: no specific menses
Gestation: about 1 yr
Number of offspring: 1 dogie
Diet
Manatees are herbivores; their nutrition consists mostly of sea grasses and freshwater vegetation.
Protect Manatees
Your purchase supports our wide range of marine conservation work - from advocating for slow-speed zones to reduce manatee collisions with boats, to fighting for the institution of protected areas where manatees spend the winter.
