In fact, there are many reasons why these whales run aground. If the whales are not particularly far from the water and in good health, then at the next high tide, these stranded whales are likely to return to the sea, and the impact of stranding on whales at this time is not particularly great. But if you run aground and stay away from the water, it is difficult to return to the sea at high tide. Moreover, some stranded whales will also have some physical problems, and it is difficult to return to the sea. Even if you return to the sea, the probability of survival is relatively low.
If stranded whales are found, then humans can also rescue them. First, people can be organized to spray some seawater on the surface of whales, because once they stay on the beach for more than 24 hours, the skin of these whales will dry quickly, so it is necessary to spray some seawater continuously to keep the whale's skin moist. In addition, some large machinery can be used to transport these stranded whales back to the sea, and the physical condition of the whales should be checked if necessary.
If the physical condition of whales is not particularly good, then it is necessary to isolate these whales and try to send them back to the sea after recovery. In fact, some whales run aground every year, but only a handful of cases have been successfully sent back to the sea. It can be seen that once whales run aground, the survival rate is really low.
