An interesting spotting. At a quick glance, you might think it's just a piece of bird dung. But it's actually a spider: a Lesser Bird-dropping Spider (Cyrtarachne bufo).
Spotted on Coney Island, Singapore, on 9 Feb 2019.

@fitheach True. :-)
But there's more than meets the eye with this kind of spider. I observed it closely for a while, but I did not see its huge spots pulsate.
Pulsate? Yes, really. See this link by Nicky Bay, who has seen this phenomenon.
Nature can look weird. That would make a great Sci-Fi monster.
