Dolphins spotted off Ha Long Bay in northern Vietnam

Specifically, images and clips of a pod of dolphins swimming at the location of Luon Cave, Ha Long Bay, Quang Ninh province, appeared on social networks on Friday morning.

A man from the Essen Grand travel agency said that at about 7 a.m. on Friday, he saw dolphins swimming on the surface of the water for about 10 minutes.

Two days earlier, two white whales were also spotted on water surrounding Van Don area.

Since 2023, many schools of dolphins, whales and seagulls have been spotted around Co To island.

Most recently, on Jan. 20, a school of about 30 dolphins were spotted in the area.

The presence of dolphins in the waters of Van Don, Co To, Mong Cai and Ha Long Bay is a positive signal for environmental protection efforts to attract marine life to Quang Ninh.
