Cyrene Reef, 26th December 2015

Although traditionally classified as a Top Shell (F. Trochidae), recent studies have shown that this species is actually more closely related to the Turban Snails (F. Turbinidae), and is now usually included in a separate family, Tegulidae.

Although traditionally classified as a top shell (F. Trochidae), recent studies have shown that this species is actually more closely related to the turban snails (F. Turbinidae), and may warrant inclusion in a separate family (known as Tegulidae).

This is one of many species inhabiting shores that will be surveyed as part of the Southern Expedition of the Comprehensive Marine Biodiversity Survey. Taking place from 20th May to 7th June, researchers and volunteers will be involved in collecting samples and surveying various marine habitats, in an attempt to catalogue the marine life that lives in the waters to the south of Singapore.
