African Penguin vs Magellanic Penguin

African Penguin

Spheniscus demersus

Huge3.1 kgMarine

African penguins grow to 60–70 cm (24–28 in) tall and weigh between 2.2–3.5 kg (4.9–7.7 lb). The beak length of the African penguin varies, usually growing between 4.8–6.5 cm (1.9–2.6 in). They have a black stripe and black spots on the chest, the pattern of which is unique to each penguin, like human fingerprints. The sweat glands above the eyes cool the birds' blood and as the temperature rises, increased blood flow causes the glands to get pinker. This species exhibits slight sexual dimorphism; the males are slightly larger than the females and have longer beaks.

Magellanic Penguin

Spheniscus magellanicus

Huge4.1 kgMarine

Magellanic penguins are medium-sized penguins which grow to be 61–76 cm (24–30 in) tall and weigh between 2.7 and 6.5 kg (6.0 and 14.3 lb). The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two black bands between the head and the breast, with the lower band shaped in an inverted horseshoe. The head is black with a broad white border that runs from behind the eye, around the black ear-coverts and chin, and joins at the throat.
