Salpsare arguably one of the strangest organisms roll around our ocean . They are n’t jellyfish , despite looking a bit like them ( afish inside a jellyfishis whole other issue ) and are in reality more close have-to doe with tohumans than man-of-war . As urochord , they feed on plankton and expend their lives go down on seawater into an unwritten syphon , promote it through a sieve - alike structure ( to scoop up up the yum ) before boot out it out the other end , known as the atrial siphon .
sure images on the cyberspace ( the above included ) might run you to believe they deplete Pisces , but these adolescent animals most likely actually swum inside the gelatinous blob on purpose .
