I think I have made this month's puzzle a little easier. There are only 18 species and I have tried to show their faces head-on or in profile, so they should be easier to identify, indeed for one or two you don't even have to identify the exact species.
But of course there is another question - which is the Odd One Out? As a possible tie-breaker, please also suggest a suitable 18th species which could replace the Odd One Out.
If you have a question, please send me a PM. Post your answers in this thread after noon UST (11 am BST) on Monday 8th June.
