可以喺好多地方容易發現嘅澳洲針鼴


針鼴科分為兩個屬,針鼴屬同原針鼴屬。喺針鼴屬中只得一個品種;而原針鼴屬現存有3個品種,另外同屬嘅兩個品種經已絕種,只有化石。



針鼴屬


澳洲針鼴(Tachyglossus aculeatus)喺新畿內亞東南部俾人發現,而且喺澳洲接近嘅地方亦發現佢哋嘅蹤跡,包括澳洲阿爾卑斯山脈同內陸沙漠地區,尤其喺螞蟻同白蟻非常多嘅地方。佢哋嘅體形比原針鼴屬動物細,但有長啲嘅刺。



原針鼴屬


原針鼴屬 3 個品種都係新畿內亞嘅「土著」,俾人捉嚟食而慢慢減少,蚯蚓同昆蟲係為嘢食,喺森林嘅樹葉堆中搵食。



  • 長吻針鼴(Zaglossus bruijni):生活響高原森林。


  • Zaglossus attenboroughi:最近發現嘅品種,喜歡較高嘅棲息地。


  • 大長吻針鼴(Zaglossus bartoni):當中有 4 個唔同嘅亞種。

絕咗種嘅兩個品種係:


  • Zaglossus robustus

  • Zaglossus hacketti


特徵




針鼴科動物捲成球狀


針鼴科係細嘅哺乳動物,成身都有毛同刺。外表上,佢哋似南美洲嘅食蟻獸同其他有刺哺乳動物,好似刺猬同豪豬。腳短有大爪,不過四肢強而有力,令佢哋成為強勁嘅挖掘者。


佢哋有細同長嘅「口鼻部」,同時有口同鼻嘅功能,但係冇牙。會撕開軟木或蟻丘,用長同埋有黏性嘅脷,將獵物黐嚟食。澳洲針鼴多食蟻同白蟻,而原針鼴屬鍾意食蚯蚓、昆蟲。


針鼴科動物同鴨嘴獸一樣,係卵生嘅哺乳動物。雌性針鼴科動物會喺交配後第 22 日,生一個有羽毛同軟殼嘅蛋,並將佢放入身上嘅「育兒袋」裏面。孵化約需要10 日時間,幼獸會從阿媽嘅乳腺啜食奶。喺育兒袋裏面約 45 - 55 日,BB 會開始生刺出嚟。呢個時候阿媽會開始挖掘籠安置 BB,約每5日返來餵一次,直至 BB 7 個月大斷奶為止。



保育現狀





香港動植物公園以前所養嘅針鼴


針鼴係一種好難成功繁殖嘅物種,目前全世界只有兩次成功繁殖嘅記錄:第一次喺1908年,喺巴林動物園(Belin Zoo)裏面成功繁殖出一隻,但係過咗3個月度就死咗;另一次喺1955年,Basel Zoo有一隻重83克,有12.5厘米長嘅針鼴出世,剛出世時佢個身好凍,雖然其後為佢保暖,但係都活唔到2日。


香港動植物公園以前亦有養針鼴。籠係喺含笑樹之下嘅草地裏面,好難睇到佢,之後擺咗落去獅狨猴籠裏面一齊養,近幾年已經唔見公園有養,相信已經死咗。
