My dad went for his usual morning walk and found this dude:
The moment I reached home from work, he eagerly came and showed me the brain. My first thought was why would he want to put a coral in the pot. On closer inspection, it appeared quite like a brain, you know.
I have my reasons for the CSI title above - I took a photo of it with my Canon A400 with a ruler to show the size of it and uploaded to Twitpic to seek the Twitter community's help to identify this species.
