•How is the penguin able to
camouflage itself?
Physics

bird camouflage while it swims in the ocean. Its
black back blends into the dark ocean when
predators look down from above, and its white
belly blends with the sunlight when predators look
up from below

Biology:
•Breeding occurs from September to February every
year.
•The female lays an average of two eggs. The male
and female take turns incubating the eggs for 40
days.
•After the eggs hatch, both parents feed the chicks by
regurgitating food.
•When chicks are about a month old, they gather with
all the other chicks from the colony in groups called
crèches. Being grouped together provides protection
for the chicks when the adult penguins leave the
rookery to hunt.
