Bathymetric limits of chondrichthyans in the deep sea

Published online on 29. October 2014 Bathymetric limits of chondrichthyans in the deep sea: A re-evaluation J.A. Musick, C.F. Cotton ABSTRACT: Chondrichthyans are largely absent in abyssal (>3000 m) habitats in most regions of the world ocean and are uncommon below 2000 m. The deeper-living chondrichthyans include certain rajids, squaliforms and holocephalans. Several hypotheses have been erected
