The penguin, the emu and the
humming bird.
The PenguinPenguins have one tube from the beak. ( the trachea) This tube goes
fora while then stopping at the syrinx, a small sac that splits into twoBronchus. These tubes lead into the abdominal sacs. The trachea is alsoan airway to the lungs. The two lungs are behind these sacs, just
slightlyabove them. Above the two lungs is the Interclavicles sac. This sac is
thelargest in a penguins body. There are smaller sacs directly underneath
thissac on the left and right. Some names include: the Anterior sac, and thePosterior sac.

Penguins have furry feathers toKeep them warm, flippers/wings to propelThemselves through the water and blackFeet flippers also to move in the water.
The EmuOne of the main reasons emus can’t fly is because their wings are two short
andThe fat breastbone feature doesn’t allow the muscles in the wings to flex out
to fly.Although, they can run very fast due to the specialized pelvic limbs. Like
humans,Emus have a gastrocnemius. To keep cool on hot days, emus use their lungs
as coolers.
