Tectus cf fenestratus (Gmelin, 1791)
37mm

This species does not quite fit any of the known Tectus species. Its shape is similar to T. pyramis, but has several rows of nodules on the whorls. The nodules are similar to T. triserialis, but the shell tends to be too wide and the largest row of nodules is right at the suture rather than back from it a bit. The sutural nodules are like those of T. fenestratus, a species that appears thicker and heavier. For now we are leaving it as T. cf fenestratus but that is subject to change. Tectus cf fenestratus is common in the Marshalls on a range of intertidal, lagoon, pinnacle and seaward reefs, where they live on and under rocks and in ledges on the hard substrate.

A younger specimen with strong nodules at the sutures.
