Tarantulas rely on side-eyes to navigate back home: Study
Spain-based researchers have found that tarantulas use their lateral eyes to track direction and distance to return to their nests after catching their prey. The study says that the 'wolf spider' species doesn't retrace its steps. Instead, it calculates 2D movements as sides of a right-angled triangle and walks along the hypotenuse of the hypothetical triangle to navigate back home.
