so i received an order of snails from liveaquaria.com, the astraea snails had some hitchhikers. both snails had another type of snail hitchhiking on its shell. these hitchhikers dont move at all, actually there shell is contoured perfect to the astraea's shell. alll they do is lift there shell when its safe and lower it when its threatend. dont have any pics, cant get a good shot yet. will have some soon. anybody have any ideas?
p.s. U.H. stands for unidentified hitchhiker
