The expression “Brother from another mother,” is used to speak about a friend that is so close to you that it seems you are siblings, even though you really aren’t. Recently this expression has widely been used on the internet as a caption for pictures showing animals of different species that strikingly resemble each other. A cat and a rabbit that look exactly alike, a dog and a horse that have a similar pattern, or a fox and an owl who look like brothers separated at birth — some of these couples look just amazing!

Bright Side has prepared for you a collection of pics showing the most extraordinary ‘twins’ from the animal world and a bonus shot that will make you smile.
