Notes on a mating event of the deep-sea crab Chaecon affinis in the Gorringe Bank (NE Atlantic)
The deep-water red crab Chaceon affinis is the largest species of the family Geryonidae. Unlike other species of the same genus, C. affinis is not yet subject to intense commercial exploitation but it has been appointed as a new target resource in European waters, in spite of the lack of information...

The deep-water red crab Chaceon affinis is the largest species of the family Geryonidae.
