If you want to be really pedantic, it should have a capital letter at the beginning, a full stop at the end and "great photo" should preferably be followed by a semi-colon although this is not vital.
Talking about the slides in the Gorilla enclosures. The babies and juveniles do sometimes use them when playing. The big males rarely though I've seen one in the original 'roundhouse' come sliding down one (standing on all fours) as a quick way to get from the top down to ground level.
Behind this male in the photo you can see the metal of the shute is very worn- probably because they still use it in their displays sometimes.
