Nodolatirus rapanus

Nodolatirus rapanus is a species of sea snail, a marine gastropod mollusk in the family Fasciolariidae, commonly known as spindle and tulip snails.

Description

The shell length reaches approximately 40–60 mm, with a robust fusiform shape and distinct axial ribs. Shell coloration ranges from pale tan to light brown with darker spiral bands.

Taxonomy

This species was described in 2013 by Bouchet & Snyder as part of a genus revision in the Journal of Conchology.

Distribution and habitat

Nodolatirus rapanus is endemic to the Austral Islands, particularly around Rapa Iti in French Polynesia.
It inhabits shallow subtidal zones among rocky substrates and coral reefs.

Ecology

As a neogastropod, it is likely carnivorous, preying on smaller invertebrates. Specific ecological studies on this species have not yet been published.

Life cycle

It likely has planktonic larvae after external fertilization before settling and maturing, similar to other members of Fasciolariidae.

Significance

Its restricted distribution and specialized habitat suggest potential sensitivity to environmental changes, although it has not been evaluated for conservation status.
