Which penguins “porpoise”?
That’s a difficult question to answer. Most likely all penguins porpoise at some point, but the largest birds, like Emperor Penguins, are not known to porpoise.
However, just because they haven’t been filmed porpoising doesn’t mean that Emperor Penguins don’t participate in the activity. African Penguins are not known to porpoise, but in the 1980s researchers observed the species porpoising. Which means that possibly all penguins porpoise at some point.
Adelie, Gentoo, and Chinstrap Penguins are known to porpoise often. King Penguins have been observed doing it occasionally as well.
