The distinction between the terms renminbi and yuan is similar to that between sterling and pound, which respectively refer to the British currency and its primary unit. One yuan is subdivided into 10 jiao (Chinese: è§; pinyin: jiÇo), and a jiao in turn is subdivided into 10 fen (Chinese: å; pinyin: fÄn).
Fleas are attracted to the warmth that the bodies of their hosts emit, vibrations and carbon dioxide, and they also like warm and carpeted environments where their hosts rest. These parasites feed on the blood of their hosts and can cause a number of conditions including skin infection and irritation, loss of hair and lethargy in their hosts.
A bite from a sand flea is most likely to occur at dawn or in the evening and night time hours on the beach or other sandy areas that are near water. Wetlands, swamplands, creeks, and lakebeds are other areas where sand fleas can be found. Sand fleas generally stay close to their breeding ground. They never wander more than 350 feet or about 100 meters from their breeding area. Sand flea swarms produce a high-pitched wine.
