Two blue whales appeared near an island in Vietnam on Tuesday morning, a local official confirmed later the same day.
The whales swam in the waters off Hon Trau Island, which is 45 minutes by canoe from the De Gi beach in Cat Khanh Commune, Phu Cat District, Binh Dinh Province between 8:00 am and 11:00 am before moving away, according to Dinh Thanh Tien, chairman of the commune.
Both of the sea mammals are estimated to be more than 12 meters long and to weigh nearly 15 metric tons.
Do Thanh Toan, a 37-year-old witness, said that the blue whales were hunting near the shore, swimming behind a school of anchovies.
Some tour guides operating trips along the De Gi beach told chairman Tien that the two blue whales had stayed in the area for two days.
The tour guides also described the whales’ hunt for anchovies and herring.
Blue whales being spotted in the waters off Hon Trau Island is not uncommon during this season every year, according to Tien.
But this is the first time the whales have been sighted in a pair, Tien added.
