In the darkness of the deep, animals strive to see but not to be seen. 👀
One deep-sea resident, Phronima sedentaria, has developed unique adaptations to do just this. Scientists have now shown that Phronima’s striking eyes evolved to help it see from within its gelatinous barrel.
Also known as the barrel amphipod, this tiny crustacean has a small pair of eyes that look to the side and a second, giant pair that looks up. Each set of eyes is composed of many eyelets that look at different points in space. Together, these eyelets form an image, like pixels in a camera.
A new study shows one of the advantages of Phronima’s large eyes—they allow the little amphipod to see objects in the deep sea at longer distances and over a wider depth range. A benefit they don’t have with their smaller eyes. But their smaller eyes are not entirely useless! They provide low-resolution vision of nearly the entire sphere surrounding them, so they don’t miss anything close by.
Vision in all directions is important for open-ocean animals since predators, prey, and mates can come from any direction, including above and below. Understanding how deep-sea animals see the world around them has inspired the development of new artificial visual systems used on innovative technology ranging from the Mars Rover in outer space to medical equipment here on Earth.
Elden Ring feels like playing a dream. When The Lands Between first opened up, to me it looked like a beautifully fragmented dreamscape. Almost like how our mind pieces together places we’ve been when we’re asleep. I wanted my first Elden Ring poster to feel dreamy.
“Inumaki-kun is kind. He doesn’t want to accidentally curse others, so he speaks in rice ball components — words that cannot carry curses. Even today, he helped me out. He tried to keep me away from danger. Even back then, he was showing consideration for my anxiety, wasn’t he?”
