    Here, we performed a population genomic study of the black brittle star, Ophiocomina nigra, covering most of its distribution range along the Atlantic-Mediterranean region.
    Found on coasts from West Norway south to the Azores and in the Mediterranean. Ophiocomina nigra is found on hard substrata, such as boulders, bedrock and gravel, on moderately exposed coasts with some water movement. It occurs from low water of spring tides to a depth of 400 m, although it appears to be rare below 100 m.
    A total of 192 specimens of Ophiocomina nigra were sampled across the natural distribution range of the species, from 10 different localities throughout the Atlantic-Mediterranean region between 2014 and 2017 (see details in Fig. 1 and Table 1 ).
    Ophiocomina nigra at a depth of 15 m. Distribution data supplied by the Ocean Biodiversity Information System (OBIS). To interrogate UK data visit the NBN Atlas. A dark-coloured brittlestar, with a round flattish central disc up to 2.5 cm in diameter. The five, thin, flexible arms are about five times the disc diameter in length.
