| Summary: | In this paper, the first documentation of egg‐guarding behaviour in an artedidraconid species, Pogonophryne scotti , through in situ photographic imagery obtained during video transects is provided. The male specimen was observed closely guarding a well‐defined multi‐layered egg mass deposited on the sea floor at 240 m on the southern South Orkney Islands shelf in the northern Weddell Sea. Egg‐guarding parental care is present in species that are distributed among all of the major lineages of Antarctic notothenioids; however, lack of information on egg‐deposition behaviours in Bovichtidae and Pseudaphritis prevents assessment of whether parental care originated prior to the origin of the Antarctic notothenioid radiation. |
