Mangrove forests form the interface between marine and terrestrial environments.
Consequently, animals from both these environments can be found in the mangroves. Few animals use mangroves as their only habitat. Some live primarily in the mangroves, while others move in and out of the mangroves seasonally, at different stages of their life cycle or even depending on the tide. Saltwater crocodiles are one of the most infamous inhabitants of mangrove areas. They do not generally nest in mangroves but are found nesting in vegetation fringing mangrove areas and vegetation where rivers adjoin coastal flood plains.
