Scientific Classification Kingdom: Animalia (Animals) |
The genus Spheniscus (scientific name: Spheniscus - "little wedge", alluding to the shape of the flippers) consists of four species of so-called 'banded penguins' within the Spheniscidae:
- Black-footed penguin (also known as African penguin and Jackass penguin) (Spheniscus demersus)
- Humboldt penguin (Spheniscus humboldti)
- Magellanic penguin (Spheniscus magellanicus)
- Galapagos penguin (Spheniscus mendiculus)
Like all penguins, banded penguins are characterized by their erect posture, stiff wings, excellent swimming ability, awkward movement on land, and coloration.The black back and white front make penguins difficult to see when swimming, helping them to blend in with the sea from above and the sky from below.
Banded penguins are distinctive by way of :
- a black-and-white head pattern with exposed facial (loral) skin
- a black horseshoe mark on their underside
The genus contains the most northerly of the penguins - the Galapagos Penguin, which lives close to the Equator
- Galapagos Penguin - Galápagos Archipelago
- Humboldt Penguin - Peru/Northern Chile
- Magellanic Penguin - Southern Chile/Argentina + Falkland Islands
- Black-footed/African Penguin - Namibia/South Africa
While Banded penguins are the most northerly of the penguins, they are associated with cold, nutrient-rich currents.

The Encyclopedia of Life (EOL) is an ambitious, even audacious project to organize and make available via the Internet virtually all information about life present on Earth. At its heart lies a series of Web sites—one for each of the approximately 1.8 million known species—that provide the entry points to this vast array of knowledge. The entry-point for each site is a species page suitable for the general public, but with several linked pages aimed at more specialized users. The sites spark ... (Full Bio)
