Magnetic fields are also deeply counterintuitive. As the Insane Clown Posse famously noted, “Fuckin’ magnets, how do they work?” Or as Warrant said to me, “I have enough trouble even understanding the stimulus, never mind trying to understand what an animal might perceive from it.” Other unusual senses like echolocation and electroreception can at least be compared to more familiar ones like hearing or touch. But I have no idea how to begin thinking about the Umwelt of a loggerhead turtle.
