The differences between stenobionts and eurybionts lie in their endurance limits. Stenobionts have narrow limits of hardiness: they exist in limited areas with relatively constant environmental conditions. Eurybionts have wide limits of endurance: they can exist over vast areas and withstand significant fluctuations in environmental factors.
Examples of stenobionts: flounder, rays – they can only exist in the ocean; hummingbirds – only in the rainforest, etc.
Examples of eurybionts: spruce, pine, birch, dog, rat, mouse, sparrow, tit, pigeon – these plants and animals are found all over the world.
