Gilded Tegula

Tegula aureotincta

Tegula aureotincta is a marine gastropod with a shell that typically ranges in size from 20 mm to 40 mm. The shell is broad and low, featuring a rough spire and a distinctive sculpture of low spiral and diagonal ridges. The coloration of the spire can be dark gray or olive, while the base of the shell is characterized by a bright yellow or orange skin surrounding the deep umbilicus. These features help distinguish it from similar species in its habitat. This species inhabits the Pacific Ocean, specifically in the low intertidal zones and adjacent rocky subtidal shores of Southern California and Mexico. Gilded Tegulas are typically found at depths shallower than 40 meters, with 90% of records occurring at depths less than about 10 meters. They are often associated with rocky environments, making them a common sight for divers exploring these regions. As herbivorous grazers, Gilded Tegulas feed primarily on algae. They are gonochoric and reproduce by broadcasting their eggs into the water, where embryos develop into planktonic trochophore larvae before maturing into juvenile veligers. Encounters with this species during dives can be quite common, as they are a familiar presence in their preferred habitats. The conservation status of Tegula aureotincta is Not Evaluated, indicating that there is currently no assessment of its population trends or threats. Divers should appreciate the role of this species in the ecosystem while observing its unique characteristics in the wild.
