KARACHI: A killer whale was spotted near Churna Island making it the first time ever the marine mammal has been sighted in the region, according to World Wide Fund for Nature-Pakistan.

In a tweet, WWF-Pakistan shared a video of the orca near Churna Island. The tweet read: "@WWFPak trained fisherman Muhammad Muneeb recorded the first ever sighting of #Orca, commonly known as killer #whales in #Pakistan, yesterday. The pod of 3 whales was spotted about 50 km southwest of Churna Island, feeding on a school of #queenfish. #SaveOurSpecies"

The killer whale is considered the most powerful predator on earth and has been reported on only a few occasions from Oman and the Persian Gulf, said the WWF-Pakistan. 

The description added: Orca "is rarely found in the northern ArabianSea. No authentic record of this species is known from Pakistani waters up till now."

Moreover, a whale shark was spotted about 10 nautical miles from Karachi harbour on Saturday, the WWF-Pakistan said. 

Contrary to its name, the whale shark is not a whale. It is a fish. In fact, it is the largest fish in the world. It can grow up to a length of 60 feet. The fish is mostly found in open waters of the tropical oceans.
