Manatee Cove Park regularly has manatees hanging out. Mullet jump around, too. It's a good place to see mangroves' roots reaching. As a premiere bull shark estuary, the Indian River Lagoon hosts up to 6ft bull sharks which may be seen as well. Manatees generally make their presence known with their nostrils, though during days with weather like on Valentine's Day, they group up and get rowdy. There's a boat landing and the site has commercial kayak tours for daytime fauna and nightime bioluminecent dino-flashlights (dinoflagellates) 🦕🔦
