Breath-hold capacities and circadian dive rhythmicity shape optimal foraging strategies in a polar marine mammal, the Weddell seal (Leptonychotes weddellii).

In LL and DD conditions, more animals exhibited arrhythmic dive behaviors (depth and duration), rhythms that differed from 24 h, and/or low-amplitude or weakly significant rhythms (Fig. 10 ).
