Looking svelte, little penguin!
Sigrid the penguin is just one of over 1,700 animals residing in Germany's Hannover Adventure Zoo. Over the past few weeks, she and each of her zoo-dwelling counterparts were weighed and measured -- a herculean task indeed!
We hope they were all as well-behaved during the process as little Sigrid, who looks like she took the weighing in stride.
