横斑锦蛇
被列入濒危物种
因其出众的外表被学界称为“世界上最美的蛇”之一
又因其安静个性和首次发现地被赋予“雅女蛇”绰号
“一切正常,确定孵化成功!”8月23日,丁利在电话中告诉记者,第一批人工孵化的横斑锦蛇很快将出世。
被列入濒危物种的横斑锦蛇,因其出众的外表,被学界称为“世界上最美的蛇”之一,又因其安静个性和首次发现地,被赋予“雅女蛇”绰号。
作为蛇类研究大家赵尔宓院士的弟子,中国科学院成都生物研究所副研究员丁利几乎接触过所有的四川蛇类,但横斑锦蛇的人工繁育成功,仍让他兴奋不已,“这一天等得太久了,从2014年7月在天全县喇叭河自然保护区捕获它们算起,已整整三年”。

“雅女蛇”的过去
其存在被质疑大半个世纪,2017年人工繁育成功
7月26日15时,中科院成都生物所科研大楼四楼实验室里,丁利科研团队成员陈泽柠博士小心翼翼拉开饲养盒,正在产卵的横斑锦蛇迅速退到盒子角落,缩成一团,警惕地看着不速之客。
这条横斑锦蛇通身黄绿,不到拇指粗。它的“丈夫”,则在不远处的另一个盒子里。
“看着吓人,其实一点毒性都没有。”陈泽柠拨开横斑锦蛇周边的沙子,约一米长的躯干露了出来,背部分布着不规则的窄横纹,头上有两条黑色横纹——“横斑锦蛇”因此得名。
自7月26日8时发现雌蛇产卵后,陈泽柠一步不离大楼,等到第二枚蛇卵出现,已是中午。说话间,他轻轻捏起一枚蛇卵,手电光照过去,微弱的毛细血管显示,这是一枚受精卵,长约4厘米,除了更为纤细外,外表与普通鸡蛋无异。
