👉 Lautropia is a biological term used in ecology to describe a species that lives on or near the surface of water, typically within the range of aquatic plants and algae. This group of organisms includes many different species, ranging from microscopic planktonic organisms like zooplankton to larger macroscopic animals like fish. Lautropia are often found in bodies of water where they can access nutrients and other resources that may not be available to other aquatic life forms.
