Soon afterwards Jason found us another whale. This is Tiaki, which means 'guardian'. Tiaki was given this name because he has been seen fighting off orca which were attacking smaller sperm whales. (They showed us a video of this on the way back to base.)
All whales are named when they are known, according to Maori custom. In particular, if whales are stranded, they are named, and important ceremonies are held in their honour if they are so unfortunate as to die on the beach.
You can see from this picture that Tiaki is quite a size. You can only see about two-thirds of his length and the top tenth of his body. We really don't want to see one this close to Roaring Girl.
