The Perth Zoo's (in Australia) echidna breeding program has produced a world-first breeding milestone. Two babies, known as puggles, are the first to be bred from zoo-born echidnas and are also the first offspring to be born to four-year old mothers. The puggles were born to first time mothers Mila and Chindi, both bred and born at Perth Zoo as part of its breeding program for the short-beaked echidnas.


The births have shed new light on echidna reproduction. Until now, it was believed female echidnas did not breed until the age of five. This breakthrough may in turn help conserve the Short-Beaked Echidna's endangered cousin, the Long-beaked echidna, which is facing extinction in the wild in New Guinea.


General Information about the Echidna

Echidnas are monotremes (mammals that lay eggs). They are also known as spiny ate eaters. Echidnas are 30cm to 45cm in length and weigh between 2Kg and 5 Kg. The body, with the exception of the underside, face and legs, is covered with cream covered spines.

The echidna is shy and moves slowly and carefully. It is adapted for very rapid digging, having short limbs and powerful claws. The echidna is common throughout most of Australia and New Guinea, in particular dry country areas. Their diet is largely made up of ants and termites.

【澳大利亞時報訊】 珀斯動物園迎來了2個新生針鼴幼崽,這是世界首次,並成為針鼴繁育史上的裡程碑。

兩個幼崽一只取名為Nyingarn(土著語“針鼴”的意思),一只取名為Babbin(土著語“朋友”的意思)。

它們是在動物園孕育出的針鼴,在世界上是首次,生它們的母針鼴今年4歲。

環境部長比爾.馬米恩(Bill Marmion)說,新生幼崽的出世為針鼴的繁殖帶來了新曙光。

至今為止,人們一直認為母針鼴要到5歲才能生育,所以這些新生幼崽的出世為針鼴的繁殖帶來光明。

馬米恩部長稱,小針鼴的出世加上其他一些通過視頻監控和研究得到的數據將有助於解開針鼴行為和繁殖的秘密。

他說:“另外,反過來又可以幫助我們保護瀕臨滅絕的短喙針鼴的表親 - 長喙針鼴。這是一種在新幾內亞即將面臨滅絕的一種野生動物。”

馬米恩先生還說,在澳大利亞僅有24只針鼴是在籠中繁殖的,其中有8只是在珀斯動物園繁殖的。

針鼴科 Tachyglossidae 有2屬2種,即針鼴 Tachygolssus aculeatus(或稱短吻針鼴)和原針鼴 Zaglossus bruijnii(或稱長吻針鼴)統稱為:echidna。

Tucking in: Staff at the zoo are feeding Beau milk which they squirt into the palms of their hands, so he laps it up like he would in the wild


...but thankfully he is now in safe hands and being cared for at Sydney's Taronga Zoo


Saved: 40-day-old Beau, a short-beaked echidna, was found alone on a dirt track...

Not sure if it is a good thing for the animal to born in a zoo, maybe wildlife better.

好奇特的動物,全身針狀似的棘毛,像刺蝟,但無牙,用長長的舌頭黏捕食物,以螞蟻及白蟻為主食,又像食蟻獸,與鴨嘴獸同為仍然生存的單孔目動物,是很難繁殖成功的動物,這"新生幼崽的出世為針鼴的繁殖帶來了新曙光",真的是值得庆賀的事
