African Penguin vs Galapagos 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.

Galapagos Penguin

Spheniscus mendiculus

Huge1.9 kgMarine

The average Galápagos penguin is 48–50 centimetres (19–20 in) tall and weighs around 2–4 kilograms (4.4–8.8 lb). It is the second-smallest species of penguin, after the little penguin. Females are usually smaller than males. Galápagos penguins have a black head with a white border running from behind the eye, around the black ear coverts and chin, to join on the throat. The top of the beaks are black and fade into pink on the bottom. They have two black bands across the breast that connect to the back, the lower band extending down the flanks to the thigh.
