In situ observation of chimaerid species in the Gorringe Bank: new distribution records for the north-east Atlantic Ocean



In the framework of the R.V. Nautilus exploration programme, remotely operated vehicle (ROV) surveys were conducted at bathyal depths in the Gorringe Bank. Video transects revealed the presence of the chimaerids Chimaera opalescens and Hydrolagus affinis in the region. An identification key for the north-east Atlantic species of the family Chimaeridae is proposed.
