拟鳄龟（小鳄龟）
别名：小鳄龟、蛇鳄龟、美国蛇龟、平背龟
分布：北美洲東部与中部，中美洲，南美洲西北部
特 征：拟鳄龟是大型龟，一般背甲长可达50CM。其头部呈三角形，顶部灰褐色，散布有小黑斑点，并有数粒小突起物，头部不能完全缩人壳内。龟的口裂较大，达眼睛后部，颈长，呈淡黄色。背甲宽短，长与宽几乎相近，成体背甲棕褐色（幼体黑色），每块盾片均有突起成棘状，且从棘的顶点向左、右、前三个方向形成放射状条纹，背甲后缘呈锯齿状。成体腹甲淡黄色或白色（幼体黑色），腹甲较小，四肢不能缩人壳内，肥大且粗壮，表皮不规则的散布小的疣粒，腹面有大块鳞片，趾、指间具强大的爪及丰富的蹼。尾长，是背甲长度的一半，尾部覆以环状鳞片，背部形成棘，似鳄鱼的尾。
习 性：鳄龟是水栖龟类，野外生活于湖、河、沼泽地及水潭，也可生活于含盐较低的汽水区，如港湾、河口湾。喜伏于水中的泥沙、灌木、杂草中。鳄龟漂浮在水中时借助其背甲上保护色，像一块烂木头漂浮在上水层，很不容易被发现。它时常将眼鼻伸出水面外，而头不完全伸出。鳄龟喜白天在水中，伏在木头或石块上，有时也漂浮在水面，有时四腿朝上，背甲朝下，头却朝上露出水面。夜晚活动较频繁。鳄龟耐寒耐热。18度以上正常觅食，22～32度是最佳活动温度；34度以上少动，伏在水底及泥沙中避暑；15～17℃时尚能少量活动，有些龟能觅食；15度以下冬眠，10度以下深度冬眠。鳄龟为杂食性，如野果、植物茎叶、小虾、小蟹、小鱼、蛆、蜗牛、蚯蚓、水蛭、小蛙、蟾蜍、蝾螈、淡水寄生虫、小型哺乳动物及各种各样的藻。人工饲养条件下，食鱼、猪肉、牛肉及家禽内脏，植物类食苹果、菜叶等。拟鳄龟生长速度非常惊人，所以目前是很普遍的肉用龟。作为宠物饲养时要注意切勿过分喂食，以免龟过分臃肿肥胖。鳄龟生活于水中，在水中觅食。喂食时应将食物投入水中或放在水边。投喂时间以上午9-10时、下午3-5时为宜。当水温为17度或以下时应停喂食物。初春、深秋少喂，春末、夏季、秋初多喂。喂食后次日应及时换水。
捉拿方法：鳄龟是较凶猛的龟种，成体鳄龟不能随意捉拿和玩赏。捉拿时，应迅速而敏捷地抓龟尾部（勿抓末端）且多抓一些，以免龟挣扎时滑落。由于龟的颈部较长，能伸长至背甲中部甚至后部，张嘴欲咬。所以抓住龟尾后要提防被咬。
注 意：成体鳄龟性情暴躁，能主动攻击人，幼体较温顺。当有人或物在龟的前方走动、晃动时，龟先将头缩人壳内，等待适时机会，突然伸出头欲咬，然后又将头缩人壳内，如此反复数次。鳄龟的腹甲较小，仅有背甲一半大。爬行时四肢将自身撑起，跨步距离大，速度快。鳄龟的潜逃能力较强，前腿攀物，依靠两后腿和尾，龟能直立，能爬树、粗糙的墙面和水泥面。因此要注意防止龟逃走，容器的高度应是龟的身体全长（头到尾的距离）的2～3倍。水质在人工饲养条件下由于容器较小，水面不开阔，龟排出的粪便及残饵均在水中，水质易污染。长时间饲养极易造成龟患病，如肠胃炎、皮肤病等。在容器内饲养鳄龟要经常换水，洗刷容器，定期消毒。换水前，先检查自来水的水质，若水的刺激味较浓表明水中含氯较高，不宜使用。拟鳄龟有厮咬现象，小空间内不宜群养。

Malayan Flat-shelled Turtle
（马来平背龟）
Distribution: Thailand, Vietnam, Malaysia, Indonesia.
（分布：泰国、越南、马来西亚、印度尼西亚）
Empire Stock: WC exported from Indonesia.
（当地市场进货渠道：从印度尼西亚进口的野生个体）
Size: Up to 32 cm.
（个体大小：最大可达32CM）
Habitat: Found in a variety of water bodies including swamps, streams and ponds.
（习性：通常生活于各种水体环境中，包括沼泽、溪流、池塘）
Diet: I feed them Mazuri Freshwater Turtle pellets and Tortoise diet, romaine, fish, strawberries, mangoes, bananas, and cantaloupe. I have been finding small soft white chunks on the pond bottom for a few weeks. Recently I discovered the source. I witnessed a Notochelys eating Oak acorns that had fallen into the water and swelled. I am not advocating feeding them acorns, just noting that they seem to like them, as there are almost no intact acorns in the pond. This is compared to other ponds in the same area that are loaded with acorns.
（食物：作者喂它们吃淡水龟粮、莴苣、鱼、草莓、芒果、香蕉、哈密瓜，比我吃得还滋润！！有几个星期作者发现在它们栖息的池塘底有一些白色的软壳，原来不知道是嘛东西，后来才亲眼看到，原来六板龟在吃从橡树上掉下来的橡子。但是作者不提倡喂六板龟吃橡子，只是好象六板龟好象偏好这一口）
Sexing: Males have longer thicker tails.
（繁殖：公龟有又长又大条的东东...这个东东是指尾巴，各位别想歪）
Breeding:
Notes: Of the turtles in the Empire this species is voted "most likely to projectile defecate when handled". It is amazing how much can come out of one small turtle. They would probably be less likely to do this if they were handled more often, but I prefer to handle as little as possible.
Care Sheets: ATC
（饲养：这一段看得我满头雾水，好象是说六板龟有“放毒王”之称，一拿在手里就吓得排大小便，作者很奇怪这么小的龟怎么能排这么多黄白之物出来，比我家那只小锯还能拉。作者还指出跟它玩熟了后，拿在手里它就不会大小便失禁了，但是还是不要老拿在手里玩，别吓到它）
These are very shy turtles and I attribute part of my success in keeping them alive the last few years to housing them in a shaded pond with plenty of hiding spots in and out of the water.
（作者说这是一种非常内向怕羞的龟，他养了几个，饲养成功了，主要归结于给它们提供了一个阴暗的池塘，池塘里面或者岸边有大量的藏身所。）

Flat-shelled Turtles
Notochelys platynota
by Russ Gurley
Comments: This interesting turtle, very rare in captivity, has a distinctive flattened, elongated, and lightly grooved carapace. It has the reputation for doing poorly in captivity but new husbandry methods, including the use of large, warm, well-planted enclosures, and advances in deparasitization and veterinary protocols, are producing successes in keeping this turtle alive and well. The bright yellow to apple-green carapaces of the hatchlings make them some of the most beautiful young turtles in the world.
（这是一种有趣的龟，但是很少人养。。。。可能有人养但养不活吧这种龟有着非常明显的扁平、伸展、略微有点凹陷的背甲。这种龟以巨难养而著称。。（huangdudu：＂比食螺还难养吗？＂）但利用新的饲养方法，比如说提供大的、温暖的、植被良好的环境，给它们提供优良的兽医服务（养活一个，不是兽医胜似兽医），那么这种龟的成活率会提高很多。六板龟幼龟的壳色从明黄色到苹果绿不等，作者认为六板幼龟是世界上最漂亮的幼龟（huangdudu:"食螺苗也很漂亮啊！"））
Distribution: N. platynota is found in Thailand, Vietnam, western Malaysia, Singapore, Sumatra, Java, and Borneo.
（分布：泰国＼越南＼马来西亚西部＼新加坡＼苏门答腊＼爪洼＼婆罗洲（一半属马来，一半属印尼））
Adult Size : Adult N. platynota grow to 13” (32 cm).
（成体大小：最大可达32cm）
Captive Care: Indoors, Flat-shelled Turtles have proven to be quite delicate. They should be offered 3” to 4” of warm, filtered water and a land area with plenty of natural hiding spots. These hiding spots can include tropical plants and small, evergreen shrubs. Piles of leaves and palm fronds will add further “security”. The substrate should consist of a layer of pea gravel beneath a layer of ½ peat moss and ½ damp sand and then topped off with a generous layer of cypress mulch to help retain moisture. A fluorescent shop light fixture with UVB-emitting bulbs and a 100-watt spotlight are placed over a basking spot. Notochelys will rarely bask, and will retreat to the nearest shelter when an observer approaches their enclosure. They are very secretive, spending most of their time hiding. They will, however, occasionally venture out after the enclosure is sprayed. They are often found in the early morning hours soaking in the aquatic portion of their enclosures. Most of their activity is during the early morning or late evening.
（饲养：在室内，六板龟是非常敏感的，应该给它们提供一个温暖、过滤良好的水体环境和大面积的、具有众多天然藏身所的场所----这是阿富汗的塔利班吧？藏身所的应该包括热带植物和小型的常青灌木丛。树叶和大片的棕榈叶可以给六板龟仔足够的安全感。陆地垫材应该包括一层沙砾，上面再覆盖苔藓和湿砂，再上面再种植一些柏木属的植物来保持水分----太夸张了吧～～～需要提供UVB灯和100瓦的聚光灯，模拟太阳光晒背----------又夸张了，照天然太阳光不就行咯？它们晒太阳晒的爽，但是如果有人接近，神经质的它们会飞快地逃到最近的藏身所藏起来。“美国飞机来啦！！！！“它们通常是偷偷摸摸的，一生大多数时间都花在躲藏和逃跑上面了，典型的萨达姆啊！但是偶尔它们也会大胆一回，跑到外面的世界冒险一回，早上喜欢在水里泡几个钟头的澎澎浴。早上和傍晚是它们活动的高峰期...）
Outdoors, Flat-shelled Turtles do well in a semi-aquatic enclosure that features land and shallow (3”to 4”) water. The land area should be planted with a variety of ground cover and larger shrubs and plants that offer them lots of secure hiding places (which they use often). Flat-shelled Turtles are especially active after rains and they thrive in warm - 80 ° to 85 ° F (27 ° to 29 ° C) environments. They have been reported to be averse to both extreme heat and bright light (Buskirk, 1997), so we make sure they have plenty of shady retreats. Outdoors, a keeper may need to turn water sprinklers on them for several hours during the hottest afternoons.
（在室外，六板龟仔比较喜欢半水栖的环境。给它提供一部分陆地和3到4英寸的浅水区。陆地种植大量的绿色植被和灌木丛，还是给它们藏身的。雨后六板龟们会很活泼，但是太高温和强光照会令它们很不爽～～所以我们要确保它们有阴凉的地方遮阴。在户外的时候，碰到中午最热的几个小时，需要给它们喷点水降温。）
Feeding: Flat-shelled Turtles are omnivores. They have been found to enjoy meals of earthworms, snails, slugs, and even crickets (Buskirk, 1997). In addition to the invertebrates, they should be offered a large and diverse salad every three days. This salad should consist of a combination of finely grated and more coarse offerings of romaine lettuce, kale, squash, carrots, sweet potato, apple, banana, cantaloupe, strawberries, and pear, as well as mango and papaya when they are available. Banana and mango, in addition to saucers of earthworms, have proven to be very effective in getting newly imported Notochelys to feed. After they begin feeding, we suggest adding some higher protein foods such as soaked commercial turtle pellets mixed in with the salad to increase their nutritional intake.
（饲养：杂食...omnivores的意思是不偏食的人，嘻嘻，要是真的是不偏食那就好养咯！喜欢吃蚯蚓、蜗牛、蟋蟀，跟黄额黄缘等半水龟的食性差不多。除此之外，每三天给它吃一顿蔬菜沙拉----我的天啊蔬菜沙拉包括搓碎的莴苣、羽衣甘蓝（这是陆龟最好的食物，磷钙比最合适）、南瓜、胡萝卜、马铃薯、苹果、香蕉、哈密瓜、草莓、梨，如果有可能还要加上芒果、木瓜。如果想它们吃得心情愉悦，那再加一碟甜品蚯蚓。这种食物对新到家的六板龟有巨大的吸引力...别说对六板龟，对人都有巨大的吸引力啊！六板龟开食后，可以适当给它加点高蛋白的食物，如龟粮，来增加它们的营养摄入。）
Common Health Problems: Dehydration, stress, and unusually high parasite loads have all proven to be part of imported N. platynota 's health problems. Many specimens have been very reluctant to feed and mortality has been high in imported specimens. A prophylactic round of Baytril® and Panacur® are recommended by several keepers working with this delicate species.
（常见的健康问题：脱水、压力挤压（运输中造成的损伤，具体情况看下面的包装图）、特别多的寄生虫！！！死亡率极高！）
Breeding: As N. platynota has the reputation of not surviving in captivity, little is therefore known of its courtship, breeding habits, or egg-laying behavior. We feel that with close supervision, an intense parasite elimination program, and a large, well-planted, “safe” enclosure, collectors will see beautiful, captive-hatched Notochelys available in the future.
（繁殖：人工繁殖极少，目前很少人很观察到它们的交配、产卵行为。作者希望通过严密的监控、有效的杀虫等方法、然后提供良好的饲养环境，来养好这种龟）

佛洲亚种：分布于佛罗里达半岛，在市面上偶有出现，但因数量上远不及模式亚种，所以经常成为鳄龟饲养爱好者追求的对象。体色偏艳黄色，头尖，颈部和四肢的突起非常多且尖锐。
成体相当巨大
野外生存环境
产卵
黄化个体
白化个体
提醒一下，鳄龟在亚洲也算是外来入侵物种。特别是国内现在正大力发展食用小鳄的人工饲养，已有不少从人工饲养场逃逸出来的个体流到野外。所以大家一定要像抵制巴西放生那样抵制鳄龟的放生。虽然规模还没有巴西这么严重，但同样是需要引起关注的。在不久的将来小鳄将成为第二代危险中国生态环境的“巴西”，且这种“巴西”的个体大的程度足以对人造成伤害。
