IMG_0080 Superb giant landsnail (Powelliphanta superba prouseorum) is our largest giant landsnail, its shell may grow up to 90 mm across and 40 mm high. A fist sized adult snail can weigh over 90g, but unfortunately old individuals like this are now rare, because possums, and at lower altitudes pigs and rats, have largely wiped them out. These massive snails are confined to the forests inland of Kahurangi Point in North west Nelson, where aerial control of possums may be this snail's only hope for survival *
