PDI = post-dive interval, IDZ = intra-depth zone dives.
Mean (±SD) and maximum dive parameters of individual female California sea lions (Zalophus californianus) from Granito Island, Mexico recorded for 15–27 days during a warm season (Jul–Aug 2005) (mean no. dives 2068±655) and for 22–89 days during a cold season (Feb–Mar 2007) (mean no. dives 8322±9511). Female IDs organized by groups produced by the cluster analysis.
