| Abstract |
The occurrence of a small specimen of Lepidion guentheri (Giglioli, 1880) (Gadiformes: Moridae) with an unusual dark colouration in the Porcupine Bank is reported. A single specimen of 114.2 mm of total length was caught in 2023 in a bottom trawl at a depth of 1168 m. The specimen was initially identified morphologically and later confirmed by molecular taxonomy using DNA barcoding. Its dark colouration pattern is discussed in the context of the known colouration patterns. Although a complete melanosis is possible, ontogenetic colouration is proposed as the most likely cause. DNA barcoding suggests the presence of Lepidion guentheri in the southern Indian and southwestern Pacific Oceans. |
