marine lake

   [ water ]

   An inland body of permanently standing brackish or saline water, occupying a depression on the Earth’s surface whose water level is commonly influenced by ocean tides through subterranean cavities connecting to nearby lagoons; generally of appreciable size (larger than a pond) and too deep to permit emergent vegetation to take root completely across the expanse of water. Such water bodies can have unique biota (e.g., sting-less jellyfish of Palau).
