Their eyes, in comparison to the rest of their body, are absolutely tiny. They’re ranked as one of the most poorly-sighted animals on the planet, up there with bats and moles.
A recent anatomical study of the black rhino’s retina at an Australian university suggests that the human form should be detectable at nearly 200 meters – 10 times the distance previously suspected and in direct conflict with what Nat Geo has stated.
Early 20th-century researcher William Bates has claimed that rhinos can at least improve their dire situation, though. His work, which isn’t universally accepted, suggests that rhinos are able to sharpen their focus by squinting and closing one eye – just like humans do.
In recent years bad news has come thick and fast: the western black rhino and northern white rhinos were declared extinct, only two northern white rhinos remained alive and, just four months ago, Iman, the last Sumatran Rhinoceros in Malaysia, died, Rhinos are far from the only big beast to be endangered by reduced numbers and resultant in-breeding.
