Ah good, I thought: spotting one of these is going to be easy.
And then I discovered that I don't have any. Nope. My nails are a uniform colour all the way down. Rats.
Ah well. I don't suppose it matters. In fact, if I do ever find time to worry about my lack of lunulae then that'll be a sign I'm leading a singularly blessed existence.
Anyway, lunulate. It means crescent-shaped.
The moon might be expected to be lunulate, and it is, though not at the moment because today it's very nearly full.
Never mind. We are surrounded by crescents in any case. Any orange, lemon or grapefruit is concealing quite a few of them. Here's a Leopard Lacewing, Cethosia cyane bearing some black crescents (it's very doubtful there are any Leopard Lacewings around at this time of year, but, hey, it's a nice picture).

Or look at this Grey Reef Shark's mouth:
Beautiful, isn't it? Though I hope for your sake not easy to spot.
Still, the shark brings us neatly to the easiest way of all to spot a crescent shape.
What is it?
Smile at people.
Do count how many smiles you have to give people until someone smiles back.
*It'd be really interesting to know the answer to this, particularly by location. Do people in rural places smile more or less than urban folk? Are city Africans better at smiling than suburban Russians? Do let me know what happens.
Spot the frippet: something lunulate. This word comes from the Latin lūna, which means moon.
