【Reptile】(I), croc and gator

        Hanging around in the Reptile Zoo for several hours last weekend, had several hundreds shots in the camera, 70 or so keepers.  I am planning to make 3 posts, crocodilians for the first one, followed by lizzards and snakes.
       

       Anyone knows the difference of crocodile, alligator, and caiman？

       Although they have important similarities that they differentiate from other reptiles, crocodiles, caimans and alligators are three distinct species.  In terms of scientific classification, these three species belong to the order Crocodilians ( Crocodilia). The alligator and the caiman belong to the Alligatoridae family ( Alligatoridae ) while the crocodile belongs to the Crocodilidae family ( Crocodylidae ).

      Here I only discuss the appreances. In the natural environment, it is possible to easily recognize these oviparous and carnivorous reptiles thanks to the shape of their jaw and their skull: the crocodile has a thinner and long snout, V-shaped unlike, and the caiman which has broad a U-shaped jaw. Another difference: in the crocodile, the fourth tooth of the lower jaw protrudes when the mouth is closed, becoming lodged in a notch in the upper jaw and visible leaving.  Crocodiles are larger than alligators and caimans, their average size is 4 meters, while it is only 3.4 meters for alligators.  The largest crocodile is the Saltwater crocodile, record length reached 6 meters, the largest Nile crocodile recorded is 5.5 meters. The weight of a crocodile increases approximately cubically as length increases.

 

1. American alligator，size:  2.4-3.7 meters，longest record 4.9 meters

3. Alligator gar ，North American local species, carnivorous fish
4.Cuvier's dwarf caiman，the smallest living crocodilian, though called dwarf, they ain't tiny，normal size:1.2-1.5 meters，the longest one can reach 1.8 meters.

7. Nile crocodile, longest record 5.5 meters

11.  This one is a question, I didn't find it name plate, it is smaller than the dwarf caiman. Want to identify whether it belongs to Crocodylidae or Alligatoridae according to the description at the top?

16.  I could not help to give big thumb-ups to this elementary first grader who read each animal's description, never stumbled or halted by new word.

This is what the description looks like that the little boy read. 17. Sulcata tortoise
Below are some scary big bugs, not reptile.  18.

Wow! what a difference between yours and mine (under APAD)!

I would like to find a hole to hide now :-)))

I like #6 theBest; but #10 makes it looks like Maowi the cat

with its gentle eye :-)

the advanced glass makes difference, I can't be any better

if I only use a phone

monster of a gentle eye?

haha. I can talk to most cats, and calm most dogs,

but I 'd stay far away from these, and run from snakes ;-)

cold-blooded creatures only go by instinct

11. it belongs to Crocodylidae.对吗？现学现卖：）我去佛罗里达看过鳄鱼，坐在船上，

离鳄鱼两米远近距离看鳄鱼，应该是Alligator。

Blanding's turtle = a python's head&neck on a fancy body.

17那张照得角度光线取景完美得就像假的一样：）最后一张是微距摄影吗？大蜘蛛？

鳄鱼两米远近距离看你: 应该是 MYSJ 妖妖灵 :-)))

是Alligator建造的佛州沼泽湿地。对佛州地理有重要影响，如今被生态被缅甸巨蟒威胁-被人当宠物又不负责任地放生

不是，后一帖大蜥蜴里有一张微距，临时换的镜头

我看了半天也觉得是某种，Croc, 或者是某种young croc

Salt Croc在澳洲，太平洋岛链。croc在非洲非洲。gator 是北美产物

Caiman 也是淡水鳄鱼

那么多Python bivittatus怎么办？好奇查了查，它没有天敌啊

按照理论 crocodile, the 4th 2th of the lower jaw protrudes嵌入上颌缺口

见过一个诡异的照片+视频，一条巨蟒死了，身体从中间断开，断开处一条大鳄鱼死在它胃里。

Python‘s head&neck on an armor～

太吓人了，它的嘴得有多大，撑S的？

every one is super. so sharp. like number 17 best.

蛇帖中我有个照片，500lbs重的巨蟒，头看着不过成人拳头大，但有弹性，能吞进比它粗好几倍的物体，好在这东西不会一日三餐

That's the prettiest turtle I've seen

Must be its basking spot, it moved a lot previously.

哈哈，学习了“晒太阳的地方”（basking spot，这词儿你以前就会？），乌龟智商一定高，不然的话怎么赢了兔子：）

鱼缸养turtle必须给它放一块basking block, 否则它体温低了新陈代谢就停止了，不吃不动，宠物店有卖

花木兄的照片真是太棒了，如此清晰，相机一定也是高档的，很享受！我就不去动脑子区分了：）

gear does matter, but the person matters more
