An aquatic ecosystem that is formed by a mixture of salt water and fresh water is known as an estuary. This type of ecosystem has brackish water, which is a mix of fresh and salt water, in an area that is partially enclosed, is fed by a river or stream and is also connected to the open sea.
There are seven types of crocodiles (based in my research) namely Indo-Pacific or the salt water crocodile, swamp crocodile, Nile crocodile of Africa, Cuban crocodile, Morelet's crocodile, Ornoco crocodile and the American crocodile.
