Cynops orientalis


Cynops orientalis
Chinese Fire Belly Lizard
中国火腹蝾螈
The Chinese Fire Belly Newt (Cynops orientalis) is a small (2.2-4 inc, 6–10 cm)  black newt, with bright orange aposematic coloration on the ventral side. Cynops orientalis is commonly seen in pet stores, where it is frequently confused with the Japanese Fire Belly Newt (Cynops pyrrhogaster) due to similarities in size and coloration. C. orientalis typically exhibit smoother skin and rounder tails than C. pyrrhogaster, and have less obvious parotoid glands.
Chinese Firebelly Newts are mildly poisonous and excrete toxins through their skin. Consisting primarily of tetrodotoxins, newts of the genus Cynops pose a medically significant threat if enough toxins are consumed (Brodie et al., 1974). Despite this, skin excretions alone are unlikely to be harmful to humans unless the entire animal is swallowed. Regardless, the washing of hands before and after contact with these or any amphibian is important to reduce the risk of transferring toxins or disease to and from the animal.
In the year 1008 AD, a Chinese author mentioned that a small black salamander could be found in the water weeds in pools on the Mou prairie. This animal had a head like a lizard and a dark red underside, four feet and four toes in paler colors. Without a doubt, this passage describes the same species that we call Cynops orientalis today.
Furthermore, this author stated that these salamanders were cultivated in the sublime lake of Tien-tse at the summit of Mount Luchan around the same time. There, they were thought to be the sons of the celestial dragon. Local peasants believed they had the power to bring rain
Chinese Fire Belly newts are one of the most commonly found species in the pet trade due to extensive collection from the wild, where hundreds of thousands of individuals are collected annually.
Cynops orientalis does best in an unheated aquarium at temperatures between 58-68 °F (14-20°C). Temperatures exceeding 74°F typically result in high levels of stress or death. Adults typically do best in aquatic habitats with some degree of land provided (turtle docks, floating plants, and certain types of driftwood function well in this regard). Failure of newts to enter the water may be a sign of stress, improper water quality, or other health problems. As a rule of thumb, five gallons of aquarium per animal is ideal, though smaller tanks may have water quality problems. A twenty gallon tank (~76L) filled 3/4 to the top can house 4-6 adults, provided the water quality requirements and other needs of the animals are met. Including live plants in the aquarium can help maintain a healthy water quality while providing cover for the newts and a more attractive enclosure.
Captive newts may eat pellets or freeze-dried foods, though some animals may refuse this. Live food items that are readily taken may include bloodworms which are the larvae of Chironomidae, earthworms, water fleas such as Daphnia, adult brine shrimp, blackworms, or mosquito larvae. Tubifex worms can carry a wide array of diseases, however, so should be avoided. Large worms may need to be chopped to suitable size. Newts may also eat tadpoles or small fish, but these food items present a higher risk of parasite and disease transmission if wild-caught.
Many times, newly purchased females are gravid and may be induced to breeding if provided suitable egg-laying sites. Water plants and plastic egg-laying strips (thin strips of clean garbage bag tied to a rock or other weighted object) work well, and plastic strips may be preferred to live plants 1. Eggs are laid singly wrapped into plants or plastic, with a few eggs laid each day. Typical clutch size may vary between 50 and 250 eggs per female. Larvae hatch after a few weeks and can be raised on baby brine shrimp, daphnia, or cut blackworms. However, due to the low demand for captive bred C. orientalis, intentional breeding is uncommon and metamorphs can be difficult to sell or even give away. After metamorphosis, this species tends to go through a terrestrial stage. At this time you would need a tank with a water depth ranging from 2.5-5.8 cm (1-2 inches). Though, this water depth can be slightly higher or lower. Heavy planting is needed; such as elodea and java moss.

耳腺发达,眼部后方无红斑。外观虽与日本红腹蝾螈酷似,然而本种却为全长90mm的小型种。即使变态为成体,体侧仍残留有侧线器官。
蝾螈躯体较小,泄殖腔孔隆起,孔裂缝长,内侧可看见明显的绒毛状突起的是雄蝾螈。躯体较大,腹部肥大,泄殖腔孔平伏,孔裂较短,内侧没有突起的是雌蝾螈
息于山地池塘或水田等静水域,以及山溪流中流速较缓的水域。春季时,会在每一水草上各产下1颗卵。幼生发育至全长35-40mm后,即可进行变态。
 可以放在大的玻璃鱼缸内饲养,便于观察其活动。缸底铺些洗净的沙砾碎石,注入30厘米深的潭水或井水,并投入少量金鱼藻等水草,布置成与捕捉场所相似的生态环境。沙石有吸附污物的作用;水草能进行光合作用,增加水中的含氧量,并供蝾螈产卵用。 饲养用水以清洁的池水为好,井水也适用。如果用自来水的话,放置3-5天后才可使用,否则自来水中殖留的氯气会导致蝾螈中毒死亡。换水是一项经常的管理工作。保持水质新鲜清洁,有利于蝾螈正常生活。冬季每2-3周换水一次,其他季节每3-5天换水一次。 蝾螈喜食活的小动物。水蚯蚓是较理想的饲料,可隔日投入少许;也可以将水蚯蚓放入单层纱布内包裹,用绳悬挂水中,水蚯蚓会从纱布空隙中伸出部分身体,蝾螈会游去拉食。此外,孑孓、水蚤等,也是蝾螈喜爱的食物。在缺乏活动的小动物时,也可将瘦猪肉切成小块喂饲。但应注意投食不可过多,以无残食为宜,防止食物腐烂而影响水质。
