American Cockroach

American Cockroach (Periplaneta americana)
Tanah Merah, 23rd August 2009

Despite its name, the American cockroach did not originate from the Americas. Instead, it is likely to be originally native to Africa, from which it has managed to spread and colonise much of the world.

Rat

Rat (Rattus sp.)
Pasir Ris, 17th June 2009

It’s interesting to see how carcasses deteriorate over time; for some reason, this rat (which was shown in this post) didn’t fully decompose, and instead became mummified. I’d first discovered the carcass in May, but by late July, which was the last time I really bothered to inspect it, it had turned quite flat and crispy.

This could be any of the following species of rat commonly found in urban areas:
