Many biological aspects of deep-water sharks are poorly known due to their rarity and difficulties in conducting detailed research on them. The angular roughshark ( Oxynotus centrina ) is a rare species, critically endangered in the Mediterranean Sea, of which records are scarce across this region. Here we present a record of a female neonate O. centrina from the south-eastern Adriatic Sea, caught by a Montenegrin commercial trawler. Scientific observers were present on-board and collected the specimen, which was subsequently analysed in the laboratory. The specimen was 225 mm long (TL), weighed 59.6 g and had an unhealed umbilical scar. To date, records of this species in the Adriatic Sea have comprised of both adult and older juvenile individuals, but no records of neonates were found in the published literature. In this work, the basic biological observations of the specimen are reported. Mnogi biološki aspekti dubokomorskih morskih pasa slabo su poznati zbog rijetkih nalaza te nedostatka detaljnijih istraživanja. Morski pas prasac ( Oxynotus centrina ) je rijetka i kritično ugrožena vrsta u Sredozemnom moru, a nalazi ove vrste na tom području su oskudni. U ovom radu se prikazuje nalaz novorođene ženke O. centrina iz jugoistočnog područja Jadranskog mora, uhvaćene od strane crnogorskog komercijalnog ribarskog broda. Jedinka je prikupljena od strane znanstvenih promatrača koji su bili na brodu u trenutku ulova, te je naknadno analizirana u laboratoriju. Jedinka je bila duga 225 mm (TL), težila je 59,6 g i imala je vidljiv nezarasli pupčani ožiljak. Dosadašnji nalazi ove vrste u Jadranskom moru uključivali su samo odrasle i starije juvenilne jedinke, dok nalazi novorođenih jedinki do sada nisu dokumentirani. U ovom radu su prikazana osnovna biološka zapažanja o analiziranoj jedinci.
