These apex predators are viewed as dangerous ocean creatures, but they deserve some respect. They keep ocean ecosystems in balance, preventing other fish populations from getting too large and having negative effects down the food chain. Staff will spread the good word and host some fun activities, including the unveiling of a new shark exhibit at 2 p.m. Speakers will focus on shark conservation efforts, including how water quality in the Indian River Lagoon affects all marine species, how local fishermen help provide data and input for fisheries management, and how each of us can make a difference. Visitors may also view the turtle hospital and stroll along the bird boardwalk, which houses recovering birds and permanent residents. Free.
