To avoid turning into midnight munchies, small fish, often no bigger than pocket change, employ a frequently observed and clever strategy:
swimming inside a salp, a type of barrel-shaped, gelatinous marine animal.
Though salps don’t conceal the hitchhikers, their thin membranes can be enough to thwart attackers.
The fish don’t seem to mind sharing their sanctuary with one another:
in this image, three diminutive jacks pack inside a salp the size of a spice jar.
