It's difficult
to believe in
this age of
dominant mammals
including man
that reptiles
once ruled the
earth. although
many species -
most notably
dinosaurs - are
now extinct,
their sixty-
million-year
reigh has to
counted as one
of the evolution
's greatest
success stories.

<食鱼鳄/长吻鳄>
|
|
这是口鼻部最细长的一种鳄,口中有约100枚尖细的牙齿,牙齿大小不一,雄性嘴尖有个突起。食鱼鳄是大型鳄鱼,体长可达6.54米,1908年曾经捕到过一只超过9米长的。
食鱼鳄分布限于印度、巴基斯坦、孟加拉、缅甸和尼泊尔的宽阔河流中,很少离开水,以鱼为食。食鱼鳄在沙地挖深洞产卵,卵铺成两层,共30-40枚,幼鳄孵出后体长就有36厘米,全身布满灰褐色条纹。食鱼鳄虽然受到法律保护,但是野外种群仍然受到各种威胁,处于灭绝的边缘。在印度的养殖场中还有一定数量,在动物园中繁殖纪录很少。
