During our English lesson today, Our teacher asked us to go on a virtual tour to Chek Jawa. Do you know that Chek Jawa is actually in Pulau Ubin, Singapore?
Previously a virtual unknown, Chek Jawa came into national prominence and focus only since the early 2000s when the area's rich biodiversity was discovered almost by chance during a nature outing at low tide. News on the impending land reclamation works planned by the government on the area sparked a rare show of public-led and coordinated effort to reverse the reclamation plans. The Singapore Government, in turn, surprised many when they acceeded to these requests in December 2001. The area has been fenced off due to an increase of tourists into the area, damaging the ecosystem in the area. Conservation efforts were made by the Ministry of National Development to preserve the area. (taken from http://en.wikipedia.org/wiki/Chek_Jawa)
The thing that attracts me most is is the red-orange sea star I saw there. It looks very colorful and on top of that, it has so many amazing features.Sea stars do not have skeketon but instead possess a hydraulic water vascular system that aids in its movements. Sea stars usually hunt for shelled animals like clams and oysters. It can regenarate any of it's five arms in a short time.Sea stars are composed of a central disc from which arms sprout in pentaradial symmetry. Most sea star have 5 arms, but some have more or fewer. Some sea stars have shown differing numbers of limbs within a single species.Above is a picture of a beach full of star fish.(Some of my sentences are copied wholesale from http://en.wikipedia.org/wiki/Seastar, but most are my comments after reading the article.Pictures taken from [http://images.google.com.sg/images?hl=en&q=seastar&um=1&ie=UTF-8&sa=N&tab=wi
