Megalobulimus oblongus




Megalobulimus oblongus (Muller, 1774)

Common Name

Giant South American snail


The shell of this species will vary in color from brown, to tan, to pinkish. There are no color markings on the shell. It may grow as high as 70-100 mm, with 5.5-6 whorls. The apertural (mouth) lip in adults of this species is pink. The umbilicus (navel) is covered by the columella (lip of mouth). This species is very similar in appearance to the giant African snails; however, obvious differences include:

  • The whorl just above the body whorl has a characteristic bulge.
  • The body of the animal has a softer, gelatinous texture, when compared to the more leathery feeling of the acahtinids.
  • They produce less slime.
