On a rock during low tide at a Sonoma County beach near Bodega, CA.
Katharina tunicata (Wood, 1815) is commonly known as the Black Katy chiton, Black Leather chiton, Black chiton, or Leather chiton. Capable of growing up to 12 cm, it's generally described as being football shaped with a black leathery girdle that embeds protective plates shaped like diamonds. Their underside is dull orange or yellow. This species is protected in the USA under the Coastal Zone Management Act. These intertidal zones are susceptible to contamination from industrial activities, timber harvesting, mining, seafood processing, as well as coastal development. Over-visitation and over-harvesting are a common concern. Effects of climate change, present and future, are not fully understood but it will likely affect the diversity and structure of the intertidal communities K. tunicata reside in. Wikipedia Wikipedia
