, the striped catch is thriving in the microgravity environment of its celestial space aquarium. That's despite the astronauts on board the station observing the fish "showing directional behavior anomalies, such as inverted swimming and rotary movement."released by the China National Space Administration, the fish are swimming in all sorts of different directions inside a glass cube, seemingly struggling to tell which way is up.
The data could shed further light on how space and cosmic radiation can impact much larger vertebrae like humans, which could have important implications for our future efforts to venture further into space.This is not the first time humans have had to entertain fish in space.
Eventually, the fish oriented their backs to the lights inside the Skylab, using light as a way to direct themselves. And the hatchlings that came on board as eggs also used light to orient themselves. But despite what looked to be a successful introduction to the cosmos, fish — like humans — suffer from bone density loss as theIn other words, further studying the behavior of fish in a near-weightless environment could prove invaluable to our understanding of the effects of space travel on human health.
