This short illustrated web site is really fascinating i think, it shows great pictures of the rosy wolfsnail (euglandina rosea) mating, feeding and egg laying.

All carnivorous snails have those mustache-like lobes sticking out from either side of their heads. Here's a document I found on the California Academy of Sciences' webpage that explains more.

Megalobulimus aren't carnivorous and they have frilly lips

Hi there, not all carnivorous snails have got those typically extended lips, like Euglandina does. Among those, who do, for example are the South African cannibal snails ( Natalina). According to Herbert & Kilburn: "Field Guide to the Snails and Slugs of Eastern South Africa" those are especially fierce predators, attacking smaller snails and devouring them piecemeal, with lots of writhing and foaming on the victim's side. The book even mentions those snails might possibly bite your finger, if you pick them up. There are, however, other carnivorous snail species, such as the Dalmatian predator ( Poiretia cornea), who do not have the extended lips. Poiretia, by the way, has a special method to overpower its prey: It dissolves the shell wall with a self-produced acid! Other carnivorous snails, occurring in Britain, are the Testacellidae, looking like slugs with a shell at the tail tip, too tiny to withdraw into. Those snails hunt earthworms underground. In that they ressemble the Paryphanta from New Zealand. There are also the Daudebardiidae, which are similar, though not directly related. Some further information: On Natalina: Natalina beyrichi and Natalina wesseliana (University of Kwazulu-Natal). On other carnivorous snails: Feeding and Nutrition of Snails (weichtiere.at). Kind regards Robert

Would it be true that not all carnivorous snail have those 'mustache' lobes, but snails that do have them are carnivorous? Just curious.

Yes, I think so. Those snails, hunting down their prey following its slime trace need poweful senses of smell and taste, which is why the lips and tentacles are extended.

The difference is that hunter snails have an extra pair called palps or lappets that are used to detect prey. The Megalobulimus just have flared anterior tentacles.
