Are manatees extinct

Manatees are not extinct, although many are injured or killed by power boats, or killed by red tide toxicity and that is what caused them to be endangered.
Manatees are not extinct. One great example is in Blue Springs Park in Orange City, Florida. Every January they hold a Manatee Festival and some of the proceeds go towards helping the manatees. The park itself is a home to these creatures as well as indigenous birds and 15 foot long gators. Manatees are also found in the St. John's River area near Sanford and Deltona, Florida. This huge winding river system may be the connection to manatees in Blue Springs.

As the river winds north towards Jacksonville, the manatees can be found along the way. St. Augustine is also a haven for these creatures in undisturbed areas. Assumably, the river system near Punta Gorda, Florida on the gulf coast-would also house these delightful mammals.
