For example, a tree snake, native to Australia and Indonesia, has wiped out native forest birds on Guam and is working its way across the Pacific — sometimes by hiding in airplane wheel wells.
Misalnya, seekor ular pohon, binatang asli Australia dan Indonesia, telah menyapu bersih burung - burung hutan asli Guam dan merambah ke sepanjang Pasifik — kadang - kadang dengan bersembunyi di tempat roda pesawat terbang.
