The biology of penguins and the species of penguins of the Antarctic seashore...
A moulting penguin is a mess!
Penguins don't have teeth, but they do have something that looks similar inside their mouths. These are backwards pointing barbs, that help grip their slippery prey and encourage the one way direction down their throat.
There are three species in this genus.
Pygoscelis papua, 'Gentoo Penguin'
Gentoo Penguins usually lay two eggs. After about a month, the two chicks hatch. Both of the parents incubate the eggs and feed the young, taking turns.
Pygoscelis adeliae, 'Adelie Penguin'.
Pygoscelis antarcticus, 'Chinstrap Penguin'.
