Dolphin stranding means that dolphins enter shallow water or beach and cannot move. To put it simply, dolphins enter shallow water, and the water level is shallow, so dolphins can't float, so they will run aground. There are many reasons for dolphins to run aground. For example, dolphins enter the shallow water area at high tide, but do not return to the deep water area in time. When the tide recedes, they may be washed to the beach, resulting in stranding.

There is also the fact that dolphins swim faster when hunting, and accidentally break into a competitive position away from the shore, which easily leads to stranding. In addition, human sonar may also cause dolphins to run aground. Because dolphins use ultrasonic waves to detect objects around them, when they encounter human sonar, they may be frightened or disturbed, causing them to enter the shoal.

Dolphins will not die when they run aground for a short time, because they breathe with their lungs and will not die immediately even if they are not in deep water. But if they run aground for a long time, they will die. Because their bodies are exposed to the air for a long time, the water in their bodies evaporates quickly. When all the water in their bodies evaporates, they will dehydrate and die. When we find dolphins stranded, we can try to call the local fishery administration department and ask them to assign professional teams to rescue them. Try not to rescue dolphins by yourself, because it is difficult to succeed in self-rescue, and it may hurt dolphins.
