The gladiator spider (Deinopis) employs a remarkable hunting strategy by stretching a rectangular net of stretchable silk between its legs and catapulting it onto prey, whether on the ground or in mid-air; to aim in darkness, it uses enormous posterior eyes that regenerate a photosensitive layer each twilight and digests it in the morning, while marking a thin white line of droppings below itself that serves as a rangefinder to calibrate the net's fall to within a few centimeters of the target.

L’araignée gladiatrice : chasse nocturne spectaculaire avec filet extensible et télémètre naturelAdded:
Hold on tight. The gladiator spider Deinopis stretches between its legs a rectangular net of stretchable silk which it catapults like a landing net onto prey on the ground or in mid-air. And to aim in the dark, these enormous posterior eyes literally reform each twilight by regenerating a photosensitive layer which it digests in the morning while it marks below itself a thin white line of droppings which serves as a rangefinder in order to calibrate the fall of the net to within a few centimeters. Yeah.
