How Big are Penguins?

Scientists calculate the penguin’s dimensions by scaling the sizes of its bones against those of modern penguin species. They estimate that the penguin probably would have weighed about 250 pounds. The largest species of penguin living today, the emperor penguin, is approximately 4 feet tall and can weigh as much as 100 pounds by comparison.

The oldest species of penguins whose fossil bones were uncovered in the Antarctic were about 37-million-years-old. These species were the largest that was ever discovered as its size is about 6 foot 8 inches. The mountainous birds were the Godzilla of aquatic birds and would have dwarfed most of the adult humans. These penguins were called the “Palaeeudyptes klekowskii.”

Ornithologist Mayr has stated that the stature of the flightless penguins became smaller since they stopped the aerodynamics skills.  There are about 17 existing species of penguins. The height of these penguins differs by age and from species to species. They are as listed below:

I got interested in penguins from a young age and as I grew I realized that penguins are such fascinating birds. I made it a mission to create a website where all information about penguins could be accessed in an easy to read format.
