Looking a little bit like a mermaid, a Florida Manatees swims through the clear water of Crystal River in Florida. Manatees require warm water to survive - only capable of living in water above 68 degrees - so they come into rivers such as this in the winter, as ocean waters turn colder. Aside from dropping temperatures, these manatees are vulnerable to a variety of other threats as well, including a loss of sea grass (their main source of food), red tide, and boat strikes. Through conservation efforts, we can ensure the survival of these creatures for years to come.
