辨别真的金钱龟(三线闭壳龟).doc

我国以前统称背部年龄生长纹的龟为“金钱龟”，所以很多朋友以为在山上捡到的巴西龟、乌龟、黄缘盒龟就是价值几十万名贵金钱龟，我们养殖场所养的名贵的金钱龟学名叫做三线闭壳龟。目前国内外市场上价格昂贵的金钱龟,则是三线闭壳龟。巴西龟都是20多元一斤，乌龟10多元一斤，黄缘盒龟3000多元一斤，而金钱龟几万到十几万一个，价格相差很远。?一看背甲三线闭壳金钱龟的背甲为棕黄色,从前端至后端有三条隆起的黑色纵线,并以中间一条最明显、最长,故有川字背龟之称。INCLUDEPICTURE \d /forum/w=580/sign=15981a13d209b3deebbfe460fcbe6cd3/60d718d8bc3eb135702c0ac0a51ea8d3fc1f443b.jpg \* MERGEFORMATINET INCLUDEPICTURE \d /forum/w=580/sign=d68e5942b0de9c82a665f9875c8080d2/f905bd3eb13533fac65d2e55abd3fd1f40345b3b.jpg \* MERGEFORMATINET 二看腹甲三线闭壳金钱龟的腹甲横断,由韧带相连,当头和四肢缩回体内时,腹甲前后端均能稍向背部收缩,所以还有断板龟之称。INCLUDEPICTURE \d /forum/w=580/sign=94df3b959f82d158bb8259b9b00b19d5/5ce3b03533fa828be3c82098fe1f4134960a5a3b.jpg \* MERGEFORMATINET INCLUDEPICTURE \d /forum/w=580/sign=f50814c9d258ccbf1bbcb53229d9bcd4/51e832fa828ba61eee0575544234970a314e593b.jpg \* MERGEFORMATINET 三看背甲下缘背甲四周下缘呈金橘黄色,故也有人称之为红边龟。INCLUDEPICTURE \d /forum/w=580/sign=db545913cfbf6c81f7372ce08c3fb1d7/d327838ba61ea8d3bac9c97f940a304e241f583b.jpg \* MERGEFORMATINET INCLUDEPICTURE \d /forum/w=580/sign=998e44f46f81800a6ee58906813433d6/6256a71ea8d3fd1f09e21f41334e251f94ca5f3b.jpg \* MERGEFORMATINET 四看腹甲（龟板）色泽呈黑色，边缘有少量黄色。（注：部分越南种在腹甲（龟板）接近头部的位置有米字型）INCLUDEPICTURE \d /forum/w=580/sign=8569e4ca830a19d8cb03840d03fb82c9/46c3a9d3fd1f4134dedcb805261f95cad0c85e3b.jpg \* MERGEFORMATINET 下图为越南种的腹甲为“米字型”INCLUDEPICTURE \d /forum/w=580/sign=265708411ad8bc3ec60806c2b28aa6c8/480efc1f4134970a7a98ad5496cad1c8a6865d3b.jpg \* MERGEFORMATINET 养龟户只要对金钱龟仔细进行四看,就能买到真正的三线闭壳金钱龟,不会上当受骗了。
