Oceans | This is the horseshoe crab. These bottom-dwellers have ten eyes! One pair work just like those of bugs: each is made up of 1,000 sensors (called the ommatidium). Another set can detect both visible and ultraviolet light. Even though their eyes seem more advanced than human eyes, they actually have bad vision. . . . . . . . #animalsofinstagram #animalplanet #animaloftheday #wild #wildlife #outdoors #animals #wildanimals #conservation #nature #animallovers #instanature #wildgeography #wildlifeonearth #ocean #animalsoftheocean #horseshoecrab
