Feeding habits
Rathouisiidae are carnivorous and feed on other gastropods, but also on fungi and plants. Bornean Atopos specialising in Opisthostoma are known to tailor their approach to the size of the prey. They hold small snails with the shells aperture-upward with the front of its foot and eat their way down. Larger ones scrape away the shell to allow access through the spire. This behaviour is thought to drive the evolution of shell ornamentation in Opisthostoma. ==References==
