How do animals recognize each other without distinguished facial characteristics?

They do have distinguished facial characteristics. Humans just suck at noticing them because we are not of the same species, nor do we spend enough time around most animals to be able to recognize them.

There's a human disorder called prosopagnosia which is the inability to recognize human faces. For instance, the way someone with this disorder recognizes people they know is by clothing, hair color, eye color, etc. They can see the face, they can see its structure, but there's a mental disconnect where it is hard to recognize it on the fly.

Could you recognize your cat from among several similar cats? Probably. Because you live with it. But when you go to the zoo and look at a monkey habitat you notice no differences because you took only two minutes to observe them. Researchers CAN recognize their animals.
