They don't have to, they have no potential threats except other hippos but they still don't use camoflauge.
sometimes it depends on the type of shark and where it lives
a artic fox protecsits self from its preditors: because they run really fast , they also protects themselves because they are very sneaky & wise animals.
one is the way their skin or fur looks like,and clamougle
they can, but they normaly live with atleast one other hippo
camaflage it
To escape pray
The hippopotamuses might not know where they are and might hurt themselves.
Yes, in Disney world, these hippos roam free in animal kingdom. there are guards with tranquilizing guns around the perimeter, but just a few. The Hippos feed themselves the fish. I am a safari driver in Disney world, so i should know.
Although hippos are herbivores, they will defend themselves if threatened. If a hippo feels threatened by a human, it will attack in order to survive because every animal has a survival instinct.
