A limpet not seen in the area before.
Observation: Have not seen this type of Limpet in this area before. I found another in the same area (orange in color) on May 28, 2017.
LEO says: Two-Spot Keyhole limpets (Fissurellidea bimaculata) have a large brown, red, orange, or yellow mantle which covers majority of the animals shell. This species of limpet can be seen on compound tunicates or sponges under rocks, or on kelp holdfasts in the intertidal to shallow subtidal zones. This is an interesting limpet observation, the keyhole limpet geographic range extents generally from the northeast Pacific coastline in Sitka, Alaska on down to Baja California in Mexico.
For more information about the Fissurellidea bimaculata Dall, 1871 or any other species, the Global Biodiversity Information Facility (GBIF) website allows anyone, anywhere to access data about all types of life on Earth, shared across national boundaries via the Internet. It provides a single point of access (through this portal and its web services) to hundreds of millions of records, shared freely by hundreds of institutions worldwide, making it the biggest biodiversity database on the Internet.
