蛤蟆 田鸡 青蛙 有啥区别

 

　　蛤蟆、田鸡、青蛙的区别：

　　1、皮肤和体色不同：青蛙从眼的后方直至后肢的基部有2条纵行的皱褶，呈金黄色或浅棕色，中央有一条浅色纵纹，后肢上有很多横列的黑色斑纹，背部是褐色或黄绿色，腹面呈白色。蟾蜍皮肤粗糙，全身密布大小不等的疣状突起，背面暗褐色，腹面乳黄色。田鸡为虎纹蛙，背面黄绿色或灰棕色，背部、头侧及体侧有深色不规则的斑纹，四肢背面有深色横纹腹面白色，咽喉、胸部有灰黑色或棕色斑纹，少数斑纹达腹部。

　　2、毒腺不同：蟾蜍有丰富的毒腺，分皮肤腺和耳后腺。皮肤腺分布在躯体的背面，所处的表皮局部增厚成“疣粒”。耳后腺在头侧鼓膜的上方。小心用针刺破耳后腺，就流出乳白色具有毒性的浆液。青蛙，包括田鸡，没有毒腺。

　　3、声囊不同：青蛙和田鸡的雄蛙口角的后面有一对声囊，发声时口腔内气体压进声囊，使它扩大成球状，雌蛙没有声囊。而蟾蜍无论雌雄都没有声囊。

　　4、输尿管和泄殖腔的连结不同：青蛙和田鸡的2条输尿管分别跟泄殖腔相连，在泄殖腔壁上有2个开口；而蟾蜍的2根输尿管则先合并成一条总输尿管，再进入泄殖腔在泄殖腔壁上只有1个开口。

　　

田鸡和蛤蟆的区别

 

　　田鸡和蛤蟆是两种常见的两栖动物，它们常常被人们混淆。但实际上，它们有很多明显的区别。

　　首先，田鸡和蛤蟆的外形就有很大差别。田鸡外形比蛤蟆小巧，通体黄褐色或者花斑，有四肢，鼓起的眼睛可以左右转动。而蛤蟆则存有很显然的扁平体形, 背部浑圆，体表平滑，呈现深灰、暗棕或者墨绿。蛤蟆身上的皮肤上有众多的疣和溪纹，让沙滩上的人们看上去就像一个个小布偶。此外，田鸡的头部圆润，口吻短；蛤蟆的头部扁平，口吻长。

　　其次，两者的生活习性也有所不同。田鸡在白天活动，而蛤蟆则在夜间活动。田鸡属于四肢类，习性喜好攀爬，而蛤蟆则更多的在地面或水中活动。田鸡通常在寒冬季节进入冬眠状态，而蛤蟆不需要冬眠。

　　最后，田鸡和蛤蟆的叫声也不同。田鸡的叫声类似“嘎-嘎-嘎”；蛤蟆则是“呱-呱-呱”的呜鸣声，有点像牛叫。

　　

　　【英文介绍/For English】：

　　

　　The difference between toad, frog and frog:

　　1. Different skin and body color: frogs have 2 longitudinal folds from the back of the eyes to the base of the hind limbs, which are golden yellow or light brown, with a light longitudinal stripe in the center, and there are many horizontal black stripes on the hind limbs. The back is brown or yellow-green and the belly is white. The toad has rough skin, densely covered with wart-like protrusions of varying sizes, dark brown on the back and creamy yellow on the ventral surface. The frog is a tiger-striped frog, with yellow-green or gray-brown back, dark irregular markings on the back, head and side, dark horizontal stripes on the back of the limbs, white on the ventral surface, gray-black or brown markings on the throat and chest, and a few markings up to the abdomen.

　　2. Different venom glands: Toads have abundant venom glands, which are divided into skin glands and post-auricular glands. Skin glands are distributed on the back of the body, where the epidermis is locally thickened into "warts". The post-auricular gland is above the tympanic membrane on the head. Carefully puncture the posterior auricular gland with a needle, and a milky white toxic serous fluid flows out. Frogs, including frogs, do not have poison glands.

　　3. Different vocal sacs: The male frogs of frogs and frogs have a pair of vocal sacs behind the mouth corners. When making sounds, the gas in the mouth is pressed into the vocal sacs, making it expand into a spherical shape. Female frogs have no vocal sacs. And toads, male or female, do not have vocal sacs.

　　4. The connection between the ureter and the cloaca is different: the two ureters of frog and frog are connected to the cloaca respectively, and there are two openings on the wall of the cloaca; while the two ureters of toad are first merged into a common ureter, and then enter the cloaca in the wall of the cloaca. There is only 1 opening on it.
