Stranded short-finned pilot whale returns to habitat in Sanya

Li is particularly concerned about Haitang's diving depth, worrying about its integration into the group. The analysis of the data from the signal tag on Haitang relieved his concerns. It shows that Haitang has gradually adapted to the wild environment, swimming toward the typical habitat of short-finned pilot whales. The maximum diving depth has increased from initially just a few meters to frequent dives in the range of 300 to 500 meters, reaching the deep-sea seabed where these deep-diving cetaceans forage.

"During this survey, we did not see Haitang, but we have confirmed its well-being," said Li.

"In the three-day journey, 12 hours of daily observations were conducted to verify the feedback from the signal tag. Within the area where Haitang has been frequently spotted, multiple short-finned pilot whale groups were discovered, with a total count reaching several hundred individuals, he added.
