King dugong, the most threatened marine mammal lives here together with the sea turtles (olive Ridley and leatherback). Located off the far northern coastline, it has reefs interspersed with 50 limestone islands, which provide vital nesting areas for migratory seabirds. The park provides a refuge for the rare sea turtles and dugongs. The unique dugong has a semi-human physiognomy and is said to be the origin of the mermaid legend. Giant clams also lie within the reefs.
Containing a diversity of landscapes, seascapes, mangroves, mudflats, lagoons, sand dunes, beaches, sand islands, raised reef islands, sea-grass beds and coral reefs, the resreve has got it all. It also has the biggest mangrove stand in Kenya with the tallest mangrove trees reaching 30 meters high.
