Around 10:20, a pod of about 15 dolphins, each weighing over 100 kg, appeared approximately 150 m from the coast of Sam Son ward. The dolphins swam quickly, leaping out of the water multiple times, attracting the attention of local residents, with one notable white dolphin among them.

Bui Duc Ky, who spotted the pod while operating his canoe and casting nets along the coast, described their playful behavior. "The dolphins moved as if they were frolicking. It's rare to see such a large number of dolphins swimming this close to shore," he stated.

Local residents suggest that the calm sea conditions and reduced boat traffic early in the year might have allowed the dolphins to approach the shore.

Local authorities consider the dolphins' presence a positive indicator for Sam Son's marine environment. This suggests improvements in water quality and the coastal ecosystem. Dolphins are sensitive to pollution, typically living in seas with abundant food and stable conditions.

Dolphins are mammals, ranging in body length from 1,2 to 9,5 m and weighing from 40 kg to 10 tons. They often live in pods of several dozen to hundreds of individuals in shallow waters. These animals are known for their friendliness towards humans and can be trained for performances.

Previously, dolphins have been sighted in some coastal areas of the central region, though these occurrences were infrequent and brief. Experts advise residents and tourists not to approach the animals too closely to avoid disturbing their natural behavior.
