These two young elephants in Kenya’s Amboseli National Park may not be siblings, but young African elephants from the same herd are raised as if they are all related. Adult elephants pitch in to raise the little ones, even if they’re not the parents. Keep this supportive family-like structure in mind today, as it’s Siblings Day. Even if you don’t have any siblings in your life, there’s probably somebody you think of as being close enough to be a sibling. So, let them know you’re thinking of them today.
