You really captured the contemplative expression on his face. The cheek pads on this 17 year old male should really start to come through over the next few years, especially now his father has left the zoo.
@Zoofan15 This was a couple of years back; from the look of recent photos I've seen, Malu's development is surging ahead as we speak! I suspect he will be a very good-looking male.
@marmolady That's good to hear. Malu is surely well on his way to becoming an impressive male like his father, Santan. I shall watch with interest to see if Melbourne Zoo import a female to breed with him in the years to come.
