Wah, Yesterday I saw a pond snail(physa) eat a bloodworm(frozen)... I didn't know snails have such big mouths. It was slowly gulping it down. Quite a sight, too bad didn't have camera with me. Didn't know they eat meaty stuff either... it would take quite a digestive system... the worm is almost as long as the bloodworm! Like 1.5 cm long and 1mm thick bloodworm.
