A striking example, despite brains the size of a pinhead, are jumping spiders of the genus Portia [13]. Portia is araneophagic, preferring to dine on other spiders. Such dining can be dangerous; if the interface of the intended dinner detec…31. Ramachandran, V.S. (1990).

In this course
Uexküll, an early-20th-century biologist and theorist of animal perception, established the concept of the *Umwelt*—the species-specific perceptual world that each organism inhabits based on its sensory capacities and needs—which grounds cybersemiotic frameworks used throughout this course. His work enables the course readings to theorize how different agents (humans, spiders, AI systems) inhabit fundamentally different informational environments and how interfaces mediate the interactions between user, environment, and representation. By treating perception as actively constructed rather than passively received, Uexküll's legacy underpins discussions of how meaning emerges from the specific coupling between an organism's capacities and its world.
