Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), [19] [20] making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating.
Gentoo penguins are the fastest underwater birds in the world. They are capable of reaching speeds up to 36 km (about 22 miles) per hour while searching for food or escaping from predators. They are also able to dive to depths of 170–200 meters (about 560–660 feet). [46]
A study has estimated that there are about 3.79 million pairs of Adélie, 387,000 pairs of gentoo, and 8 million pairs of chinstrap penguins in their particular areas, [7] making up 90% of Antarctic avian biomass.
