I haven't played Pathfinder in a while and am starting up a new game soon. I want to make sure I am clear on this rule.
The Ape, Gorilla is listed here. Does he have to use a full round action to attack with BOTH slams or is this considered a standard action for him?
Unless a creature has a special ability that specifically says otherwise, everything works exactly like it does for a player character.
In this case, a single attack with a standard action, or all of its attacks as a full round action.
