In this file photo made available by the U.S. Navy, a Bottle Nose Dolphin, leaps out of the water in front of Sgt. Andrew Garrett while training near the USS Gunston Hall in the Arabian Gulf. Attached to the dolphins pectoral fin is a pinger device that allows the handler to keep track of the dolphin when out of sight. The Navy said Feb. 12, 2007, it is reviving a proposal to send dozens of dolphins and sea lions trained to detect and apprehend waterborne attackers on a mission to patrol a military base in Washington State.

在這張美國海軍提供的檔案照中，一頭瓶鼻海豚從中士蓋瑞特前騰空躍起，他們正在阿拉伯灣登陸艦岡斯頓霍爾號附近受訓。一具聲脈衝發聲器安裝在海豚胸鰭上，即使海豚不見蹤影，操作者仍可持續追蹤它的行蹤。海軍今天二月十二日說，正在檢討送數十頭海豚和海獅受訓的計畫，並在華盛頓州軍事基地擔負巡防任務，以偵測及逮捕水上攻擊者。 圖／美聯社
