MorphologyRead full entry
Katharina tunicata is a medium sized chiton, with an average length of 7 cm. Its black girdle almost completely covers the eight whitish plates, leaving a diamond shaped pattern down the dorsal side. The plates are sometimes overgrown with algae, so they will appear green (Mohler 1997). Like most chitons, K. tunicata is oval shaped, but when removed from the rock it will ball up (Karleskint 1998). The underside of K. tunicata is commonly peach colored,and houses the gills and mouth. The foot is surrounded by mantle and is usually darker orange.
