Height of dorsal vs tail - I looked on the web when we got back and there really isn't much that's configured like that and also has the potential to get that big. As noted, it's either a meg (extinct) or a grandma white that is huge. There's a lot of scuttle about big whites off Northland/Barrier, the commercial fishing boys go on about 'Brutus' which was rumoured to be a white of about that size. Dunno...
