Question

Why is the front part of the penguin white and not the back part? ​

Answer 1

Answer:

When seen from above they disappear in front of the dark blue of the ocean, while their white bellies help them to blend in when seen against the bright sky from below. According to this idea, the black-and-white plumage helps penguins to be invisible to predators and prey alike.

Answer 2

thats because the back part of the penguins need more heat and from front part the glide which makes their body cool and not very hot abd the dive to keep themselves cool and refresh
