据和记百科网站「望断江南岸」消息,近日,锦花蛇是脊椎动物吗,请问蛇是脊椎动物吗?引发热议,锦花蛇是脊椎动物吗同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。
蛇是脊椎动物。脊椎动物的体内有由脊椎骨构成的脊柱,而蛇的身体细长,分为头、躯干和尾三部分,但是蛇没有四肢,并且周身被鳞;头部形状各异,鼻孔位于吻侧,而且蛇的脊椎弯曲幅度是所有脊椎动物中最大的。蛇是肉食性动物,所吃的动物种类很多,从无脊椎动物到各类脊椎动物。
蛇的生活习性:
蛇是一种体温随气温而变的变温动物,因为蛇本身没有完善的体温调节机制来产生和维持恒定的体温。蛇类活动的最适温度是20-30℃,在这适宜范围内蛇的生长速度也随气温上升而直线上升。空气湿度对蛇类也有很大影响,一般以50-70%为宜。蛇的活动与外界温度、湿度、光线以及食物密切相关。在这些外界环境条件的作用下,出现了明显的季节性和昼夜性的特性。
当然有脊椎,蛇属脊椎动物门爬行纲蛇目,任何蛇都有脊椎骨,锦蛇也不例外.
【英文介绍/For English】:
Snakes are vertebrates. Vertebrates have a spine composed of vertebrae, while snakes have a slender body that is divided into three parts: head, trunk and tail, but snakes have no limbs and are scaly all over the body; the heads have different shapes, the nostrils are located on the rostral side, and Snakes have the largest curvature of the spine of any vertebrate. Snakes are carnivores and eat a wide variety of animals, from invertebrates to various vertebrates.
Habits of snakes:
Snakes are ectothermic animals whose body temperature varies with air temperature, because snakes themselves do not have a well-established thermoregulatory mechanism to generate and maintain a constant body temperature. The optimum temperature for snake activities is 20-30°C, and within this suitable range, the growth rate of snakes also increases linearly with the rise in temperature. Air humidity also has a great influence on snakes, generally 50-70% is appropriate. The activities of snakes are closely related to the outside temperature, humidity, light and food. Under the action of these external environmental conditions, obvious seasonal and diurnal characteristics appeared.
