Project Don Cray

Profile

Test Subject : Don Cray the crayfish [1].

Common Name : Red crayfish
Scientific Name : Procambarus clarkii

Description : 
A typical of most shrimp-like crustaceans, characterized by a joined head and thorax, and a segmented body, which is sandy red, dark blue in color. Size about 7.5 cm (3 inches) long. The head has two pairs of sensory antennae and a pair of eyes on movable stalks. The appendages, or pereiopods, of the thorax include four pairs of walking legs which, as well as walking, are to probe cracks and crevices between rocks looking for food. Don cray own one pair of clawbearing chelipeds, which it extends in front of its body while moving. These strong pinchers are specialised for cutting, capturing food, attack, and defense. It also has several pairs of specialised food handling "legs," bailers to cycle water over the gills, and five pairs of swimmerets which are under the abdomen. All of these "legs" can be regenerated if broken off. Like all other crustaceans, it have a hard outside skeleton. This jointed exoskeleton provides protection and allows movement, but limits growth. As a result, crayfish regularly gets too big for its skeleton, sheds it, and grows a new larger one. This is called molting. and occurs six to ten times during the first year of rapid growth, but less often during the second year. For a few days following each molt, crayfish have soft exoskeletons and are more vulnerable to predators.

Food : Prawn pallets, Anchovies, Carrot, dead fish (river guppies), dead shrimp, pond snails

Sims Social 在2013年6月14日正式停止服务

真是不可思议，The Sims Social 尽然将要在2013年6月14日正式停止服务了！虽然我现在已经没什么玩了，但是回想起曾经也花了不少心血时间去购买升级它，真是遗憾啊。。。 以下是从Sims Social官方论坛摘下来的公告：
 
“The Sims Social is shutting down on June 14th.

We want to inform everyone in our community that as of June 14th, The Sims Social will be retiring on Facebook.

We know that you may be disappointed by this. Retiring games is never easy, we hope you've enjoyed playing The Sims Social as much as we enjoyed making it. Thank you to all of our passionate and dedicated players for supporting The Sims Social. We hope to see you in some of our other titles on Facebook and other platforms.”

知道了此事之后我更加不想玩了（浪费时间）。在它还未正式消灭人间之前我先替它拍了张照来留念，再会吧。。。
