Researcher of the Indonesian Institute of Sciences (LIPI) Oceanographic Research Center, Sekar Mira, explains the alleged causes of stranding dozens of dolphins on Batu Tumpeng Beach, Bali.
He suspects that the strandings of 13 dolphins were caused by two factors, namely hunting activities of marine predators such as sharks, or the occurrence of tides as a result of the lunar eclipse that occurred on Wednesday (26/5).
Extreme tides affect dolphin-stranding conditions. When the tide is very high, it could be that the fish are playing in very shallow waters.
It was reported that several stranded dolphins had bites from sharks. The bites, said Sekar, are thought to be among the causes of dolphin strandings.
Previously, as many as 13 dolphins surprised residents in the Batu Tumpeng Beach area to Jumpai Beach, Klungkung, Bali on Thursday (27/5) night. The dolphins with a size of 1-2.5 meters were found stranded on the coast. One was reported dead.
The researchers were currently planning to perform necropsy or surgery on the animal for laboratory tests to find out the cause of death and strandings of the dolphins.
