A gorilla's surprising and heartfelt gesture toward an infant leaves everyone in awe.

Animals are some of Earth's most fascinating, engaging and unique creatures. Most animals are a joy to observe quietly. That's likely why there are endless puppy and kitten videos on YouTube, and it also explains why a handful of television networks are dedicated to the actions and hijinks of animals.

When an animal is involved, always expect the unexpected. Anyone who is a pet owner knows this to be 100 percent true. When you think you know how your dog or cat will react in a particular situation and environment, they surprise you, often in the sweetest and most hilarious ways.

A clip posted on social media shows the wholly unexpected and sweet way a gorilla responded when it encountered an infant. In the 22-second video, someone holds a newborn up to the gorilla enclosure while the massive animal, from behind the thick plastic barrier, sits and stares at the baby.

The gorilla appears to be entirely enchanted by the tiny human. The giant animal does not take its eyes off the baby and remains focused on the precious infant.

The woman holding the baby asks the infant, "Do you see the monkey?" While the baby cannot yet speak, it still gives a response. The child's eyes widen noticeably as if the baby does see the creature in its peripheral vision. That's when the gorilla does something so cute, heartfelt and entirely unexpected.

The gorilla purses its lips together and kisses the plastic barrier, which perfectly lines up to be on the child's left cheek.

That simple but loving gesture from the gorilla makes for an adorable and heartfelt moment. You'll likely respond in awe as you watch it repeatedly, taking in the massive animal's loving and precious move.
