BOXFISH: The boxfish’s bony rigid box-shaped carapace helps it to maneuver around the nooks and crannies of a coral reef.

BOXFISH:   In 2015 scientists at the University of Antwerp, Belgium learned its secret.  The boxfish uses the vortices–little water tornadoes–created by its unusual shape to stabilize itself.

BOXFISH: The boxfish has a stiff caudal fin (The caudal fin is the tail fin.)

PENGUIN FLUID DYNAMICS:   The emperor penguin has one of the most unusual ways in the animal world to achieve power swimming.

PENGUIN FLUID DYNAMICS:   There are 118 species of penguins. From the 70-pound emperor penguin to the tiny two-pound fairy penguin. 

PENGUIN FLUID DYNAMICS: The mother penguin places her egg on her feet.

PENGUIN FLUID DYNAMICS:   When Emperor Penguins set out on long pilgrimages, they turn themselves into flipper-powered toboggans and zip down hills lightning fast.

PENGUIN FLUID DYNAMICS: Emperor penguins have over 90,000 feathers–100 feathers per square inch!  

PENGUIN FLUID DYNAMICS: The emperor penguins preen and fluff their feathers to fill them with air before diving. With their bible-technique, they can rocket out of the water and land 50 feet up on craggy icebergs feet first.

PENGUIN FLUID DYNAMICS:   Air that was trapped in the penguin’s feathers is released as tiny micro-bubbles.
