It’s one adorable photo.

The photo, which was posted Monday on the zoo's Facebook page, included a caption that read, "As he gets older, Gus is exploring more and more of the world around him, which includes encounters with new friends like Braylee of Fort Worth."

The zoo asks followers on its page to send photos of their "animal encounters" via Facebook messages.

The zoo has gotten a lot of positive comments on the photo.

One commenter wrote: "Cutest picture ever, Fort Worth Zoo." Another commenter wrote: "Is there a certain time that is best to see Gus? My girls are dying to see him."

However, some people weren't too happy that Gus was stuck behind the glass at the zoo.

KDFW shared the photo on its Facebook page on Tuesday, and one commenter wrote: "Out of all the animals at the zoo these make me the saddest. They are so human like and just out for display. They should be in a forest somewhere roaming free."

Gus, the first lowland gorilla at the Forth Worth Zoo, was born Dec. 5, 2015.
