This preprint documents an unexpected and potentially significant observation linking the previously published Universal Consistency Operator Theory (UCOT) [1] to the behavior of a living organism. Three frequencies—f1 = 137.042 Hz, f2 = 357 Hz, f3 = 125.08 Hz—which arise naturally from UCOT as primitive invariants, were played using a sound generator. When the generator was gently touched to the web of a house spider (presumably of the Pholcidae family), the spider consistently and repeatedly approached the sound source. This response was specific to the UCOT frequency triplet; manually shaking the web or playing random music from YouTube videos elicited no such reaction. This observation suggests that the UCOT frequencies, although derived theoretically, may possess biological relevance and be specifically detectable by an arthropod’s sensory system. This document serves as the primary documentation of the phenomenon, and further controlled experiments are warranted. ---- The Arithmetic of Infinity: Quasi-Periodic 3 Torus Structures as Projections of the Universal Consistency Operator Theory https://doi.org/10.5281/zenodo.18776958 The Universal Consistency Operator Theory: Complete Derivation of Physics from First Principles https://doi.org/10.5281/zenodo.18722109
