[(Title)] Killer whale mother finally lets dead newborn calf go, after 17 days.

A killer whale has stopped carrying her dead newborn calf after at least 17 days, during which she covered 1,000 miles (1,600km), scientists say.

科学家说，在带着夭折的幼鲸巡游17天，1000英里（1600公里）后，一只虎鲸妈妈终于结束了她的“伤心之旅”。

The whale "vigorously chased a school of salmon with her pod-mates in Haro Strait" off Canada's Vancouver Island, the Center for Whale Research said.

鲸鱼研究中心说，在维多利亚海岸附近的哈罗海峡，人们看到这头鲸鱼正在“匆匆追逐”鲑鱼。 。

"Her tour of grief is now over and her behaviour is remarkably frisky."

“她的伤心之旅现已结束，她现在行为敏捷。”

Killer whales have been known to carry dead calves for a week, but scientists believe this mother "sets a record".

据悉，科学家发现虎鲸能够携带尸体一周左右，但科学家认为这头母鲸“创造了记录”。

The mother whale - known as J35 - has captivated the world's attention in the past few days.

这头编号为J35的母鲸在过去几天中已经吸引了全世界的关注。

"Telephoto digital images taken from shore show that this mother whale appears to be in good physical condition," CWR said in a statement on Saturday.

CWR在周六的一份声明中说：“从海岸拍摄到的电视数字图像显示，这只母鲸的身体状况良好。”

"The carcass has probably sunk to the bottom of these inland marine waters of the Salish Sea [between Canada and the US], and researchers may not get a chance to examine it for necropsy (autopsy of an animal)."

"幼鲸的尸体很可能沉入了加拿大和美国之间萨利什海的海底，研究人员可能没有机会进行尸检"。

The mother whale was first spotted carrying her dead calf on 24 July, off the shore of Vancouver Island.

7月24日，在温哥华岛海岸外首次发现鲸母鲸带着她幼崽的尸体。

The calf is believed to have died the same day. The cause of death is unknown.

Both Canada and the US list the Southern Resident killer whale as endangered. The whales depend on Chinook salmon - which have been in dramatic decline in recent years - for food.
