Every animal lives inside its own unique version of reality based on its specific template of sensory abilities. This is called that animal's "umwelt":
An umwelt is the unique, subjective sensory world and perceptual experience that a specific organism or species inhabits. Coined from the German word for "environment" or "surroundings" by biologist Jakob von Uexküll, it describes how different creatures in the same physical space experience entirely different realities based on their unique physical senses and brain functions.
Key Aspects of the Concept
Subjective Universe: Every living creature filters the objective physical world through its own sensory organs.
Functional Circle: Organisms continuously sense signals from their surroundings, react to them, and change their behavior based on that feedback loop.
Species Differences: Two animals can share the same space—like a dog and a human in a garden—yet experience vastly different worlds due to contrasting senses like smell, hearing, or sight.
Examples in Nature
Ticks: Rely almost entirely on temperature, the smell of sweat (butyric acid), and touch rather than sight or hearing to find a host.
Mosquitoes: Males detect the specific pitch of a female's wing vibrations, a sound completely imperceptible to humans.
Bats and Fish: Navigate using air-compression sound waves (echolocation) or weak electrical fields instead of relying strictly on visual light."
Thus it is that animals live inside and interact with their own filtered version of their environment much as we do ourselves. This feedback loop between the animal's umwelt and how they respond to implies an iterative evolution of the animal and its umwelt. The prototypical beginnings of selfness and privacy rooted in this inherently perspectival nature of embodied sentience. Selfness and subjectivity then as situational and relational instead of some inherent and in-itself property of the body. Embodiment itself an effect of one's subjective and iteratively generated environment. Our collectively-shared human umwelt as Heidegger's Dasien of being-in-the world. The possible foundation for a pragmatic and functionalist interpretation of consciousness instead of as an accurate/illusory representational simulation of the world
