長尾毛絲鼠分布範圍

長尾毛絲鼠(英文:Long-tailed Chinchilla,學名:Chinchilla lanigera)又稱絨毛絲鼠長尾栗鼠毛絲鼠絨鼠等名稱。主要分布為南美洲安第斯山脈上的高原,範圍從智利北部至祕魯南方。牠的皮毛十分柔軟細滑,一個毛細孔有50根毛,因此體毛看起來較為蓬鬆,體重約500~800公克,體長22~38公分,所以身體看起來較胖,尾巴較長,長約7~15公分。早期獵人為求長尾毛絲鼠的皮毛,遭大量的捕獵之後,如今野生長尾毛絲鼠已所剩不多,據信目前大約只剩下千隻左右,歸類為瀕危物種,被CITES列入附錄一等級的保育名單中[2]

長尾毛絲鼠是屬於夜行性生物,常在夜間活動覓食,因消化道較長,所以主食是含有高纖維、低脂肪的草料,比如樹皮、樹根、仙人掌,偶爾吃小型昆蟲,是為雜食性動物,另外為了補充活動所消耗的水分,也會利用晨間傍晚的露水做為補充水份的來源。長尾毛絲鼠的棲地選擇於海拔三千~五千公尺山區,為藏匿來逃避天敵,大多築巢是選擇在灌木林與草原裡石縫。長尾毛絲鼠在八個月性成熟,懷孕期111日,全年僅產1、2隻,野外平均壽命約八到十年。

特点

宠物绒毛丝鼠

“lanigera ”一词被译为“背着羊毛大衣”,然而绒毛丝鼠并没有羊毛大衣,取而代之的是自己的毛皮。他们的毛有2-4厘米(0.79-1.57英寸)长 ,并且有灰色、白色和黑色的带;这些毛不仅顺滑,而且又极其柔软,牢牢着在皮肤上。 在仅一个毛囊中,可长出多达75根毛,直径为5-11毫米(0.20-0.43英寸) 。 感觉毛数量多、强壮、长度长(100-130 mm (3.9-5.1 in)) ,同样从单个毛囊中涌现出来。[3] 它们上半部分的颜色一般是蓝色或银灰色;下部是黄白色。 绒毛丝鼠的尾巴背面有长而粗颜色为灰色或黑色的毛发,靠近身体附近的长达30-40毫米(1.2-1.6英寸) 长,靠近尾巴尖端的有50-60毫米(2.0-2.4英寸)长 ,并且在尾巴尖端附近会形成一个超过脊骨50毫米长(2.0英寸)的刚毛。

绒毛丝鼠在野外的繁殖期集中在十月和十二月,即南半球的春天。[4]

Running chinchilla

绒毛丝鼠生活的区域气候通常十分严苛,夏天日间阴影处温度可达 30°C,晚间气温会降至7°C(冬季会降到冰点下)。[4]
