Sinonim | |
Taipan pedalaman (Oxyuranus microlepidotus), juga dikenal secara umum di Australia sebagai Taipan barat, Ular sisik kecil atau Ular garang,[6] adalah jenis ular senawan yang sangat mematikan dari marga Oxyuranus (Taipan) suku Elapidae yang endemik di wilayah semi-gersang di Australia bagian tengah.[7] Suku Aborigin yang hidup di wilayah tersebut menamai ular ini Dandarabilla.[8]
Etimologi
Nama spesifiknya, microlepidotus, berasal dari kata micro="kecil" dan lepidos="sisik", merujuk pada sisik dorsalnya yang berukuran kecil.[9]
Penemuan spesimen
Ular ini pertama kali ditemukan oleh Frederick McCoy di tahun 1879 lalu dideskripsikan oleh William John Macleay di tahun 1882, namun untuk 90 tahun kedepan, hewan ini merupakan misteri bagi Komunitas ilmiah karena selama 90 tahun itu tidak ada lagi penemuan spesimen, dan hakekatnya tidak ada lagi tambahan Pengetahuan ilmiah mengenai hewan ini sampai akhirnya reptil ini ditemukan kembali di tahun 1972.[8][10]
Deskripsi fisik
Panjang ular ini mencapai 2,5 meter. Namun yang sering ditemui panjangnya 1,8 meter.[11] Sisik dorsal berjumlah 23 baris di bagian tengah tubuh, ventral 220-250 dengan sisik anal tunggal, subkaudal 55-70 dan seluruhnya terbagi di tengah.[9]
Warna tubuh ular ini biasanya cokelat tua atau oranye gelap, namun itu tergantung pada musim. Tidak seperti kebanyakan ular, warna tubuh ular ini selalu berubah setiap pergantian musim. Pada musim dingin, warna tubuhnya cenderung cokelat gelap dengan kepala dan tengkuk (leher belakang) berwarna hitam mengkilap. Sedangkan pada musim panas, warna ini memudar menjadi oranye-kuning cerah atau kuning pucat dengan kepala dan tengkuk berwarna sama dengan badannya.[11]
Bisa
Taipan pedalaman dianggap sebagai ular paling berbisa di dunia; berdasarkan nilai Median dosis letal dalam tikus, untuk setiap tetes bisanya, sejauh ini mengandung tingkat racun terbesar dari segala ular - bahkan banyak dugaan racun ular ini lebih kuat daripada Ular laut[12][13][14] – dan hewan ini memiliki bisa paling beracun dari segala reptil ketika dites pada kultur sel jantung manusia.[15][16][17] Tidak seperti kebanyakan ular lainnya, taipan pedalaman adalah seekor pemburu khas mamalia yang menjadikan bisanya teradaptasi khusus untuk membunuh hewan berdarah panas.[18] Diperkirakan bahwa satu gigitan mengandung bisa yang cukup untuk membunuh setidaknya 100 manusia dewasa,[19] berdasarkan pada sifat gigitannya, ada potensi untuk membunuh seseorang hanya dalam 30-45 menit jika tidak ditangani.[20] Ular ini sangat cepat dan lincah yang bisa menyerang dengan ketepatan yang ektrim,[21] Sering mematuk beberapa kali dalam satu serangan,[22] dan menyuntikkan bisa dalam setiap kasus gigitan.[23]
Kebiasaan
Meski benar-benar berbisa dan menyerang secara berbahaya, berbeda dengan Taipan pesisir yang cenderung agresif, taipan pedalaman biasanya cukup pemalu dan tertutup, dengan watak yang tenang,[24] dan lebih memilih untuk kabur dari masalah.[25] Namun hewan ini akan mempertahankan dirinya dan mematuk apabila dipancing,[26] salah ditangani,[27] atau jika dicegah kabur.[28] Karena hewan ini hidup di lokasi yang terpencil, taipan pedalaman jarang berhubungan dengan orang-orang;[29] oleh karena itu ular ini tidak dianggap sebagai ular paling mematikan di dunia secara keseluruhan khususnya dalam segi watak ular dan kematian manusia per tahunnya.[30] Sebutan "Ular garang" disini mengacu pada bisa yang dimiliki ular ini, bukan pada prilakunya.[31]
