animals have evolved a number of

animals have evolved a number of different adaptations to survive here

different adaptations to survive here

different adaptations to survive here the most noticeable one is that they’re

the most noticeable one is that they’re

the most noticeable one is that they’re all incredibly light in color

all incredibly light in color

all incredibly light in color and you see that the white sands one is

it’s incredibly important for them to be
