"Gundlachia lucasi" is a species of minute freshwater snail or limpet, an aquatic pulmonate gastropod mollusk or micromollusk in the family Ancylidae, the river limpets.

These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch". This serves as a gill as, in their non-tidal habitat, these limpets never reach the surface for air.

Distribution

This freshwater limpet is endemic to the North Island of New Zealand.

Habitat

These tiny limpets are found attached to stems and undersides of leaves of aquatic plants in quiet waters.

hell description

The shell of this species is very small, conical, with convex sides, the apex at the posterior third. It is a semi-transparent horn colour, usually covered by a blackish coating. The septum is not visible.

The shell length is up to 4 mm, the width up to 2.75 mm, and height up to 1.5 mm.
