Order: NUDIBRANCHIA Suborder: DORIDINA Superfamily: ANADORIDOIDEA Family: Polyceridae Subfamily: Polycerinae (Rudman, 2002) Thecacera pacifica is a species of sea slug, a nudibranch, a marine gastropod mollusk in the family Polyceridae. It is sometimes also nicknamed Pikachu Nudibranch due to its resemblance to the Pokémon character Pikachu (Wikipedia).

Gazelle : The Palestinian Biological Bulletin – Number 163 – July 2018

This species is known from the African coast of the Indian Ocean (Mozambique) to Indonesia and Vanuatu. It has also been reported from the Gulf of Mexico, Atlantic Ocean (Wikipedia) This polycerid nudibranch is translucent orange in colour with black tips to the rhinophores and gills. The rhinophore sheaths are edged with black with a patch of blue at the widest part. This blue colour is also present at the tip of the tail and at the tip of the lateral papillae beside the gills, separated from the orange of the body by a black band. Some specimens have black linear marks on the body with blue centres (Wikipedia). Thecacera pacifica is characterized by its orange body, its extrabranchial processes, extrarhinophoral processes and the 'tail' are white tipped diffusing into blue then into a black band. The rhinophores are orange with a black apex, the gills have a black line along the outside (Köhler, 2017). Pretty similar is Thecacera sp. 01 which has black spots on the body and black tipped extrabranchial processes (Köhler, 2017). Gazelle : The Palestinian Biological Bulletin – Number 163 – July 2018

Maximum Size: 20-30 mm. Identification: This is a translucent-orange animal decorated with black bands shading into electric-blue and white (Pittman & Fiene). Natural History (Hawaii): On Maui in Hawaii, Thecacera pacifica is known from only a few animals found along the leeward coast at 8-18 m (25-60 ft). Some were crawling on sand, others on debris or Halimeda kanaloana. It has also been found in a moderately protected rocky habitat on the Kona coast of the Big Island at 3-6 m (10-20 ft) (Pittman & Fiene). Distribution: The Pikachu Nudibranch is known from the Indian Ocean, Atlantic Ocean and the South Pacific Ocean. It lives in the Gulf of Oman, off the Eastern Coast of the United Arab Emirates.
