Interesting. I've seen these crabs in the mangroves, although not as common as other mud crabs.

"NUS researchers Peter Todd and Ian Chan, from the university’s Department of Biological Sciences, believe this is the first known example of such light-focusing external structures used for signalling in animals."

Bought a garden cart of the landcare group. Going there I kinda threw it on top of the trailer but it wasn't good and did make the trailer too wide to fit easily through the anti-bicycle barriers along the bike path. So going home I clipped it to the back to the trailer and towed it. #LegalInAustralia

Not shown: the vege shop dumpster dive on the way home so I could get compost. Made the chickens happy :)
