From historical expedition diaries to whole genome sequencing: A case study of the likely extinct Red Sea torpedo ray

Zoologica Scripta, Volume 53, Issue 1, Page 32-51, January 2024.
Abstract Torpedo rays (Torpedinidae, Torpediniformes) are small to moderately large batoids that produce an electric discharge. They are distributed worldwide in temperate and tropical seas and are, as a result of their bottom‐dwelling behaviour, susceptible to trawl fishing and often end up as victims of bycatch.
