New records of Leptacanthichthys gracilispinis and Microlophichthys microlophus (Actinopterygii: Lophiiformes: Oneirodidae) from the subarctic Atlantic Ocean, including new lophiiform barcoding data and a rare observation of a copepod parasite in ceratioid anglerfishes
In an ongoing effort to document and/or validate taxonomic identifications and monitor fishes in the subarctic Atlantic Oceans, including the production of pragmatic identification material, two new distributional records of ceratioid anglerfishes are presented: Leptacanthichthys gracilispinis (Rega...
