The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North‐eastern Atlantic) in 2021 by bottom trawling.

Gaidropsarus Rafinesque, 1810 is a genus of marine teleost characterized by a high ecological diversity and by species inhabiting from the intertidal zone to the deep-sea. Several taxonomic conundrums have been historically present in this taxon due to its conservative morphology and the lack of available specimens. Species delimitation analyses we...

Infestations by shell-boring polychaetes have been gaining attention in recent years due to the harmful effects that their presence can pose to the growth and production of marine bivalves worldwide. The Galician region, located in the north-western corner of the Iberian Peninsula, is one of the major producers of marine bivalves in the word and th...

Chondrichthyans (sharks, rays and chimeras) are a fascinating and highly vulnerable group of early branching gnathostomes. However, they remain comparatively poorly sampled from the point of view of molecular resources, with deep water taxa being particularly data deficient. The development of long-read sequencing technologies enables the analysis...

Abnormal body coloration (malpigmentation) in fishes usually occurs as either a deficiency of pigmentation (albinism or hypomelanosis and xanthism or xanthochroism) or as an excess (melanism or hypermelanosis). Malpigmentation in fishes has been extensively studied in the context of aquaculture, but it has been largely overlooked in natural populat...

Marine ecosystems have been traditionally exploited by coastal communities in several ways, especially by fishing. More recently, aquaculture has emerged as an activity through which coastal communities have diversified their economies. Thus, many regions of the world face the challenge of allowing both activities to maximise their yields while com...
