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.
Penguin eggs are smaller than any other bird species when compared proportionally to the weight of the parent birds; at 52 g (2 oz), the little penguin egg is 4.7% of its mothers' weight, and the 450 g (1 lb) emperor penguin egg is 2.3%. [62]
The weight ranges from 22.7 to 45.4 kg (50 to 100 lb) and varies by sex, with males weighing more than females. It is the fifth heaviest living bird species, after only the larger varieties of ratite. [10] The weight also varies by season, as both male and female penguins lose substantial mass while raising hatchlings and incubating their
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.

Sphenisciformes (from the Latin for "wedge-shaped") is the taxonomic order to which the penguins belong. BirdLife International has assessed 18 species. 16 (89% of total species) have had their population estimated: those missing are the king and little penguins , both of which have been assessed as being of least concern .
