Insects. Someone shivers from the sight of these chitinous creatures, someone has an appetite, and only scientists do not get tired of having purely scientific interest in them.
More recently, South African scientists have come to a truly sensational conclusion: scarabs can navigate by the stars! And to be precise, not along with individual celestial bodies, but along the entire Milky Way at once. As it turned out, beetles in the dark are capable of navigating along with it no worse than birds, and if you close their eyes with a special visor, then they completely lose orientation and stop rolling their dung ball in the right direction.
