Pacific Sideband (Monadenia fidelis)

…a medium-sized species of terrestrial air-breathing Monadeniid gastropod mollusc which is endemic to the Pacific Coast of North America, ranging from southern Alaska to northern California. Pacific sidebands average sises of 22-36 mm wide, making them the largest species of snail native to the US state of Washington.

Decollate Snail (Rumina deccolata)

…is a species of terrestrial Subulinid snail that was originally native to the Mediterranean region (except for the south east), but has now been introduced into North America, and occasionally Great Britain. Decollate snails are voracious predators and will feed readily on other snails, slugs and their eggs. They will also eat plant matter, and other invertebrates such as annelids. This has caused them to be a serious pest in the US as they will consume native species.

Limax cinereoniger

…a large species of terrestrial keelback slug (Limacidae) which occurs throughout Europe, occurring almost everywhere in Scandinavia and in the extreme South. L. cineroniger is widely considered to be one of the largest species of land slugs, with individuals possessing lengths exceeding 20 centimeters! Like other slug species, L. cineroniger occurs in woodlands and feeds on a range of organic material.

Lehmannia melitensis

…is a species of airbreathing keelback slug (Limacidae) which is distributed throughout the Mediterranean where it is known to occur  in Malta, Italy, the Aeolian Islands, Sicilia, Sardinia, and the Tuscan Archipelago. Like most slugs, Lehmannia melitensis occupies moist areas and feeds on a wide range of organic materials.

Sphincterochila candidissima

…is a species of terrestrial air-breathing Sphincterochilid snail which is known to occur in Italy, Malta, and other surrounding areas. S. candidissima is fairly small with individuals only growing shell widths of ~16-25 mm ( 0.6 -0 .9 inches). Like other members of its family Sphincterochila candidissima is xerothermophilous, meaning it is well adapted to hotter/dryer places.

Meridolum gulosum

…is a species of air-breathing terrestrial Camaenid gastropod mollusc which is endemic to Australia, where it is restricted to the rainforests and vine thickets of the Illawarra Escarpment, south of Sydney. Where it occurs from Bulli Pass south to Wollogong. Like most terrestrial gastropods M. gulosum is typically encountered among the leaf litter, and among fallen trees, rocks and bark.

Succinea putris

…is a species of amber snail (Succineidae) which boasts a large northern Palearctic distribution, occurring throughout most of Europe (including the British Isles) and part of Russia. Like most members of its family S. putris is typically seen in wet areas like on vegetation near river banks and marshes, where it will feed on a range of plant matter.
