[^1]\n\nA study conducted by the University of Bristol in the United Kingdom determined that the social behavior of spiny fish enables them to feed even in turbid waters. [^2]\n\nChristos Ioannou stated that the spiny fish managed to compensate for the challenge of reduced visibility by modifying their schooling formation behavior. [^3]\n\nProfessor Christos Ioannou stated that when unexpected food appeared in cloudier water, it took the fish longer to find it, but they compensated by changing their shoaling behavior to become more coordinated. [^4]\n\nResearchers from Bristol's School of Biological Sciences observed that in murkier water, fish took longer to move toward food than those in clear water, but individuals in larger groups responded more quickly overall. [^5]\n\nResearch led by Christos Ioannou, a professor of Behavioral Ecology at the Faculty of Biological Sciences, revealed that fish movement and coordination determine how quickly they can reach food. [^6]\n\nThe mechanisms of these fish allow them to face river pollution caused by human industrial activities such as mining, agriculture, and construction. [^7]\n\nDr. Sean Rands noted that finding these rules change in response to environmental challenges is reassuring, as it shows the fish have extra tricks for changes humans are causing to their homes.
