The meerslug family is a family of slug-like creatures introduced in Pikmin 3, although the family went unclassified until Pikmin 3 Deluxe. Members are known to dig through the ground (usually sand) and lure prey into traps. It is named after its only member, the Sandbelching Meerslug. Members belong to the Gastropoidae genus.
The Sandbelching Meerslug is a boss in Pikmin 3 and the third major boss encountered in Story Mode. It is a light brown, amphibian-like creature resembling a lamprey, with very small eyes, thick purple lips and two rows of large, sharp teeth. Further down its body, it gets wider and harbors spike-like protrusions. It is one of the largest Pikmin bosses to date.
The "Gastropoidae" genus comes from the real-world class "gastropods", which encompasses most slugs and snails.
