The genus Tectonatica Sacco, 1890 View in CoL on Giglio Island

So far, one species of the genus Tectonatica has been found alive on Giglio Island. T. sagraiana is common in sublittoral areas at depths of 10 m and below. It is well known for the Mediterranean Sea and lives infaunal directly under the sand surface. Specimens of T. sagraiana were found crawling in the sand in the Bay of Campese between 7 and 15 meters depths in large groups of 20 to 30 individuals. The specimens were collected both at day and night. The animals leave an easily observable trail on the sand surface. In contrast to other naticid species, T. sagraiana does not bury very deep in the sand.

Molecular analysis of larval stages of Naticidae indicated a related additional species to be present in the waters of Giglio Island. Four independent marker gene sequences obtained from randomly collected egg collars suggest a close relationship to T. sagraiana ( Figs. 1 View FIGURE 1 , 11 View FIGURE 11 B/b). One further species of the genus Tectonatica closely related to T. sagraiana is known from the Meditteranean: T. rizzae (Philippi, 1844) which has been described as a rare species in the Mediterranean Sea living at greater depth (> 10–100 m). Unfortunately, no shells were found on Giglio Island, so far, and no live-collected adult T. rizzae was available for sequencing. The sequences were obtained from larvae hatched from collected sand collars.
