    Eye - why-animals-do-the-thing I'd make an educated guess that that southern stingray has no idea the person isn't just a weird rock.

    Font - Here's the thing: stingrays can't see underneath their bodies. That's why they've evolved specialized organs that let them sense the electricity released by small animals moving under the sand; bottom-feeding species have to hunt with their eyes looking the opposite direction of their mouths. Reading the NBC article that's linked, it sounds like the diver was already near the seabed (maybe actually resting on it) before the ray decided to settle on top of him. It describes the ray as hove

    Font - If this was investigative behavior, I would expect to see something more than just resting on top of the diver. The best explanation of stingray investigative behavior I've ever heard was "imagine a vacuum cleaner that looks curious." They'll try to bite at or put their mouth on things they're interested in, and it frequently comes with a lot of back-and-forth motion as they use their sensitive undersides and the electricity-sensing ampullae of Lorenzini to learn more. Given that it's imp

    Font - i-draws-dinosaurs Follow there are many benefits to being a marine biologist carlyrockerthedestroyer Follow I've been here! This is a spot named stingray city. Sting rays like to hang out around here. There are boat tours on calm days where tourists come to interact with them. They stick around because they get fed, but because it's just a large sand bar, they can leave at anytime. If I remember correctly they had to slow down the feeding a bit as some of the sting rays were getting quite
