Puffins and Penguins


Puffins (left pic) live north of the equator along the coasts, they both dive and fly, and tend to walk like a duck (horiz. axis).
Penguins (right pic) live south of the equator along the coasts, they only dive, and tend to hop or walk (vertical axis) somewhat like a human. Some species of puffins & penguins may look similar due to eco-niche convergent parallels, but they are not closely related.

Penguin ice island, they flock tightly to avoid the seals, orcas and sharks of deep water.

thanks to jewel for noticing my marine mammal center 'penguin' t-shirt was actually a puffin t-shirt (my oops), got me checking out the difference between the two. But why does the marine mammal center feature birds anyways?

To a marine mammalogist, available bird population may limit growth rates in interesting species.

I agree with you Nathan, it just seemed funny to have puffins but no mammals on the marine mammal center tee-shirt. I visited the center last year, great place.
