A very suitable early zoology book, that skims the young reader through prehistory and then has a survey of the world's current wildlife, splitting the critters up into types for our perusal on very pictorial double-paged spreads. It has a lot to cover – there are a lot more types of animal than there are, say, planets – see the rest of the series for those – and this also has to factor in what things are not, as it has to tell us which is an alligator and which a crocodile, how we differentiate between dragonflies and damselflies, and so on. We also close with biological concepts, such as symbiosis, migration, etc.
I'd almost mark this down due to the unnecessary and very unfunny speech bubbles some of the creatures have been given, but no – this is still a four-star series whichever way I look.
