Latia neritoides is a species of small freshwater snail or limpet, an aquatic gastropod mollusc in the family Latiidae.

Sculpture consisting of microscopic rather distant radiate striae, and fine dense concentric growth-lines.

Apex posterior, extending a little beyond the margin, with a spiral nucleus of 1 whorl, visible on the right side.

[2] The aperture is large, oval, the thin sharp margin generally rounded, but the posterior part of it is occasionally straightened and forming more or less distinct angles with the lateral sides, which themselves may become almost straight.

[2] Further details on its morphology and internal anatomy are given in Meyer-Rochow & Moore [4] These animals are bioluminescent and highly phosphorescent.

The light stems from a luminescent slime that is emitted by the snail when it gets disturbed or is attacked by a predator such as a crayfish, an eel, or even a dragonfly nymph.
