About Thecacera pacifica (Bergh, 1884)
Thecacera pacifica is a species of polycerid nudibranch. This nudibranch has a translucent orange body, with black tips on its rhinophores and gills. Its rhinophore sheaths have black edges, with a blue patch at their widest section. Blue color also appears on the tip of the tail and the tip of the lateral papillae that sit beside the gills; this blue area is separated from the body's orange tissue by a black band. Some individual specimens have black linear markings on the body that each have a blue center. This species has been recorded ranging from the African Indian Ocean coast at Mozambique, to Indonesia and Vanuatu. It has also been reported from the Gulf of Mexico in the Atlantic Ocean.
