The Malleus Monstrorum ( a supplement for Call of Cthulhu) has stats for Deep One shark hybrids, and werewolves in it. Or you could peruse Rome and find the Kynoprosopoi, dog headed men, which are pretty much wolf men. Runequest Land of the Ninja has stats for the Kojin, shark headed men. As for half giant stats the Cercopes or Kallikantzari stats in Cthulhu Invictus might do.
Some non humanoid octopus men appear in the old Stormbringer supplement Rogue Mistress.
