Hello @Hix! SeaWorld San Diego has never had an orca that was actually named Namu. If they said it was, it was one of the old stage names like Shamu. This is a male orca as you can tell from the body structure including the severely flopped over dorsal fin. Male orcas in captivity have a 99% average of having their dorsal flop over while for females they rarely ever completely flop over. Also looking at details such as his patches and melon this is definitely Winston.
