seen? The single spotted reef crab we saw was caught in
a drift net on Sisters Island.
Features: Body width to about
9cm. This crab has a distinctive pattern of large spots on a beige
to pink body. It has four blunt spines between the eyes.
It is more active at night.
Human uses: According to SeaLifeBase,
it is collected extensively for food. While it is reported as poisonous,
tests could not confirm it. Possibly the crab becomes toxic for a
short period after feeding on poisonous molluscs.
Status and threats: Our Spotted
reef crab is listed among the threatened animals of Singapore.
Like other creatures of the intertidal zone, they are affected by
human activities such as reclamation and pollution.
