New evidence of the occurrence of Knoutsodonta Pictoni (Nudibranchia, Onchidorididae) in the Northern AdriaticFortič, Ana (Avtor) Trkov, Domen (Avtor) Lipej, Lovrenc (Avtor) Fantin, Marco (Avtor) Ciriaco, Saul (Avtor) The authors present new data on the recently described nudibranch Knoutsodonta pictoni Furfaro & Trainito, 2017 in the Gulf of Trieste (northern Adriatic Sea). We hereby present the first record of this species in Slovenian territorial waters. A total of 22 specimens of K. pictoni were recorded by diving in the period from 2017 to 2021 at five localities in the Gulf of Trieste. All specimens were found in precoralligenous habitats in the depth range of 5 to 9 m, feeding on the encrusting bryozoan Reptadeonella violacea (Johnston, 1847). Numerous finds indicate that this only recently described and therefore little known nudibranch is much less rare than previously thought.20212024-08-01 08:11:56Neznano19978UDK: 594.36:591.9(262.3)ISSN pri članku: 1408-533XDOI: 10.19233/ASHN.2021.31COBISS_ID: 94163715sl
