Ola Khalaf‟s Nudibranch (Diaphorodoris olakhalafi) is a species of dorid nudibranch in the family Calycidorididae. It is found in the Gulf of Oman off the eastern coasts of the United Arab Emirates and the Musandam Governorate of Oman (English Wikipedia). Ola Khalaf-Nacktkiemer Diaphorodoris olakhalafi (Khalaf, 2017) ist eine Art aus der Unterordnung der Nacktkiemer, die zu den Hinterkiemerschnecken und somit zum Stamm der Weichtiere gehört. Die Nacktkiemer werden im Volksmund auch als Unterwasser-Nacktschnecken bezeichnet. Diaphorodoris olakhalafi lebt in flachen Gewässern im Golf von Oman (German Wikipedia). Diaphorodoris olakhalafi (Khalaf, 2017) est une espèce dans la subordination des Limace de mer, ce qui est donc l'un des Opisthobranchia et à la racine des mollusques. Les nudibranches sont communément appelés limaces sous-marines. Diaphorodoris olakhalafi vit dans les eaux peu profondes dans le golfe d'Oman (French Wikipedia).

Family: Onchidorididae Genus: Diaphorodoris Species: Diaphorodoris olakhalafi Khalaf, 2017

Description and Distinctive Features Length of Diaphorodoris olakhalafi is between 5 - 9 mm. General body-colour is white. Body elongate-elliptical, bluntly rounded at both ends. The white mantle is ovate with the posterior end of the foot extending behind the end of the mantle. Foot produced behind in a fairly long tail, the anterior end abruptly rounded and simply labiate. The mantle is covered sparsely with small conical tubercles and the five or six gills are attached in a common pocket. The colour of the conical tubercles is white or yellow. Oral tentacles broad lobiform, with a slit-like mouth between them. The gills and rhinophores are orange-red. Rhinophore-sheath with smooth margin. Branchial plumes 5 - 6, small, simply pinnate, completely retractile within a cavity with smooth margin. Integument with spicules. There is a distinctive yellow band at the edge of both the mantle and the foot (Khalaf, 2017).

This photo triggered the search for the new species: The Ola Khalaf‟s Nudibranch (Diaphorodoris olakhalafi Khalaf, 2017) from the car cemetery ground in Khorfakkan Sea, in a depth of 19 meters.

Gazelle : The Palestinian Biological Bulletin – Number 159 – March 2018

Size Diaphorodoris olakhalafi grows between 5 - 9 mm long.

Diet This species feeds on encrusting colonial bryozoans (Khalaf, 2017).

Habitat Diaphorodoris olakhalafi was found in sea water in a depth between 2 – 20 meters (Khalaf, 2017).

Distribution The species Diaphorodoris olakhalafi lives in Khorfakkan & Dibba Sea, eastern coast of the United Arab Emirates, and the eastern coast of the Musandam Sea, Sultanate of Oman, Gulf of Oman, Arabian Sea, Indian Ocean (Khalaf, 2017).

Conservation The species Diaphorodoris olakhalafi is endemic to the Gulf of Oman region. This species is rare and must be protected (Khalaf, 2017).

Etymology / Derivation of the Scientific Name The scientific name Diaphorodoris: Diaphanous Doris. From Medieval Latin diaphanus, from Greek diaphanēs, from dia „through‟ + phainein „to show‟. Doris in Greek mythology, wife of Nereo, nymph of the waters and mother of Nereids.; and olakhalafi is Latin for my wife the Diver & Underwater Photographer “Ola Khalaf” (born 1975) (Khalaf, 2017). This new Khorfakkan Nudibranch species was classified and named by the PalestinianGerman Zoologist Prof. Dr. Norman Ali Bassam Khalaf-von Jaffa in May 2017, and the Gazelle : The Palestinian Biological Bulletin – Number 159 – March 2018

specific name „olakhalafi‟ was named after his beloved wife “Ola Mostafa Esmail Mostafa Khalaf” (born in Sidon, Lebanon in 1975) (Khalaf, 2017). My beloved wife is an active diver and PADI Dive Instructor and is a professional underwater photographer. Diving is her main hobby and passion. She photographed and published many of her underwater photos, and she is contributing to our knowledge of the magnificent creatures living in our seas and oceans. The naming of this new species is a special gift after 20 years of marriage (Khalaf, 2017).
