Kummalisus

Kummalisus is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae. The genus was first described by H.S. Slodor, however, J. Hall's original description in 1861 is cited as the primary reference to the genus. Kummalisus species are primarily found in tropical and subtropical regions of the world's oceans. These snails inhabit shallow water environments, often near coral reefs or rocky shores.

Species of Kummalisus snails have banana-like shells with pit and narrow aperture at the top of the spiral aperture. These features distinguish them from other related species. The coloration of Kummalisus shells varies depending on the species, but typically consists of shades of yellow, white, brown, red, or a combination of these.

Feeding behaviors of Kummalisus snails have not been extensively studied. However, given the genus' classification as pyramidellid mollusks, it is inferred that they engage in predator-like behavior and feed as the inhabitants of their ecosystem. Some specimens of Kummalisus contain fossilized organisms inside their shells. It's assumed these were foraged during their lifetime or obtained through processes unrelated to feeding behavior.
