Final answer:
The incorrect statement about marine teleosts is that they are exclusively found in freshwater; they inhabit various aquatic environments, including marine ones, and have a bony skeleton and swim bladder.
Step-by-step explanation:
The statement that is false about marine teleosts is that they are exclusively found in freshwater environments. Teleosts are actually a diverse group within the bony fish that can be found in various aquatic habitats, including both freshwater and marine environments. These fish are characterized by a bony skeleton, the presence of a swim bladder for buoyancy control, and they usually have bony or ray-like fin supports.
Marine teleosts are not exclusively found in freshwater environments. They are a type of bony fish and have a swim bladder. They do not have a bony skeleton.
