Figure 2: Evolution of dive duration during the first trip to sea in two elephant seal species. from Contrasting offspring dependence periods and diving development rates in two closely related marine mammal species

Development of dive duration throughout the first trip to sea in northern (n = 4) and southern elephant seals (n = 9) estimated from generalized additive models. The solid lines represent the means, and the shaded areas represent the 95% confidence intervals. Marginal density plots represent the spread of data for each species. Dive duration of 11.15 min is reached on the first day of northern elephant seals' trip to sea and in 125 days for southern elephant seals.
