Gentoo Penguins can dive as deep as 200 meters and stay underwater up to 7 minutes. During deep dives, Gentoo penguins reduce their heart rate from 80-100 beats per minute (bpm) down to 20 bpm.
After breeding, female Gentoo’s lay two eggs that weigh about 130g each (4.6 ounces). Gentoo parents then switch incubation duties on a daily basis. The incubation period lasts about 35 days, and then the Gentoo penguin chicks stay in the nest another 30 days before forming crèches.
