Knowledge of the three-dimensional movement patterns
of elasmobranchs (sharks, rays and chimeras) is vital to
understand their ecological roles and their exposure to
human pressures. To date, comparative studies among
species at global scales have mostly focused on horizontal
movements, however, threats to elasmobranchs vary with
depth, as do the techniques used to monitor them. This
study compiles the first global synthesis of vertical habitat
use by elasmobranchs from data obtained by deployment
of 989 biotelemetry tags on 38 elasmobranch species.
Elasmobranchs displayed high variability within and
between species in their vertical movement patterns.
For example, the oceanic whitetip shark (Carcharhinus
