Age validation in Octopus vulgaris beaks acrossthe full ontogenetic range: beaks as recorders of life events in octopuses

This study demonstrates the daily deposition of increments in Octopus vulgaris beaks for both lateral wall surfaces (LWS) and rostrum sagittal sections (RSS). Forty-nine marked wild animals kept in aquaria (weight range, 158–3,521 g) and 24 captive-reared known-age individuals (paralarvae, 0–98 days...
