See a Rescue Effort to Save 10 Stranded Whales
Scientists aren’t sure why the massive Sperm Whales suddenly beached themselves in Indonesia.

Saving one 40-ton Sperm Whale (Physeter macrocephalus) is a huge feat—so when 10 live Sperm Whales washed ashore off the coast of Aceh in northeastern Indonesia, it required a small army of wildlife volunteers.
In an emailed statement from WWF Indonesia, representative Aryo Tjiptohandono said the WWF team, environmental officials from the Indonesian government, and the Indonesian Navy were dispatched to Ujung Kareng Beach on Monday morning. Posting live updates on their Facebook page, the local conservation group Whale Stranding Indonesia commented that rescue groups were working around the clock to save the Whales.
Successfully moving Whales back into the ocean requires trained professionals with the right equipment, and some luck. A Whale stranded on a beach can usually only survive a day or two before succumbing to exposure, said Heidi Pearson, a professor at the University of Alaska Southeast. Pearson has assisted with saving stranded Whales in Alaska.
“One of the main concerns is their organs collapsing under their weight,” she explained. At sea, Whales are more buoyant, but once their bodies are out of the water, gravity begins to take hold. Whales can also suffer from sunburns and dehydration.
Drone footage shot by WWF Indonesia shows a messy tangle of ropes and people struggling to wrangle the Whales from shallow waters. Tug boats were used to pull the Whales out to shore, but other rescues have been conducted using a modified stretcher and cranes.
By around midnight Indonesian time, five of the Sperm Whales were successfully floated back out to sea. Several hours later, rescuers were able to move two back to sea. Early this morning, three were pronounced dead, and one of the refloated Whales returned to shore and died.
Wildlife officials aren’t sure what caused the stranding. Accounts of Whales beaching themselves have been documented for centuries, but finding the whales still alive is less common.
“Before we could get our expert to conduct necropsies on the four carcasses, the situation on the ground was getting out of hand as masses started to swarm the area,” said Tjiptohandono. He claimed residents wanting to help swarmed the beaches, making it difficult for rescuers and researchers to move the Whales and collect samples.
Without having more detailed reports from the carcasses, it’s difficult to know exactly why the whales became stranded.
Many float to shore and become stranded when they’re sick, said Pearson. Whales have also become stranded after losing their sense of direction.
“A third reason is they’re group forming. One member of the group might strand, and the other members will also strand because their bonds are so tight,” she said. “Healthy animals will strand because they’re good friends.”
Whales have also stranded because of sonic or acoustic interference. The animals communicate via underwater sonar and calls, so large vessels or disturbances in the water can interfere with their ability to navigate.
Most frustrating, Pearson conceded, is “sometimes we just don’t know.”
While a stranding en masse is less common than an individual whale floating ashore, the event in Indonesia is far from the largest involving cetaceans. Eighty-two dolphins (False Killer Whales) (Pseudorca crassidens) mysteriously beached themselves in Florida earlier this year, and the largest stranding recorded took place in 1946, when 835 Killer Whales (Orcinus orca) beached themselves in Argentina.
In 2016, more than 30 Sperm Whales beached themselves at the edge of the North Sea. An impressively large amount of plastic was found in their bellies, but the stranding was attributed to a lost sense of direction. Sperm Whales have a huge geographic range and are found throughout the world’s oceans, but whaling during the late 19th and early 20th centuries reduced their population numbers by more than 60 percent. Today, they’re classified as vulnerable by the International Union for the Conservation of Nature.
WWF will continue to monitor the six rescued Sperm Whales in Indonesia via drone to ensure they stay safely in the water.

Indonesia: Four Sperm Whales die in Indonesia beach rescue
14th November 2017;
Four Sperm Whales (Physeter macrocephalus) stranded on a beach in Indonesia have died, a local official said Tuesday, despite frantic efforts to save the massive mammals.
The Whales were among a pod of 10 spotted by locals stranded along Ujong Krueng beach in Aceh province Monday, with one seen farther out in the water.
Rescuers tried to push the nine beached Whales back out to sea as hundreds of curious locals looked on, some snapping pictures.
Five were pushed back and survived but four died, some with their mouth agape as small waves crashed over their giant bodies.
Rescuers tied ropes to the tails of some of the mammals to pull them to deeper water.
“We had problems evacuating them due to a lack of experience and equipment,” Aceh nature conservation agency head Sapto Aji Prabowo told AFP.
“But this is a good lesson for us because Aceh is a crossing point for marine mammals so in the future we should be prepared to deal with situations like this.”
An official autopsy will be conducted on the Whales to determine the cause of death, but Prabowo said the giant gray creatures may have followed their leader to shore or lost their way.
“Usually, Sperm Whales will avoid going into deep water if they’re sick. Two of them were sick. So, we assume the leaders were sick and the others automatically followed them to the beach,” Prabowo said.
One Whale had wounds that suggested it had been injured by a coral reef, he said, adding that the four dead will be buried close to the beach.
This is the second time in the last few years that Sperm Whales have been found beached in northernmost Sumatra island, with one found dead on a beach in Banda Aceh in 2016.
Also last year, eight Pilot Whales died after a mass stranding on the coast of Indonesia’s main island of Java.
They were among a group of more than two dozen Short-finned Pilot Whales (Globicephala macrorhynchus) that had come ashore during high tide.

Indonesia: Four of 10 beached Whales in Aceh die
By Gemma Holiani Cahya and Hotli Simanjuntak, 14th November 2017;
Four out of 10 Sperm Whales (Physeter macrocephalus) that were beached at Ujong Kareung Beach in Aceh Besar regency in Aceh died in the early morning on Tuesday while the rest had been taken back to open waters.
Around 50 rescuers from various offices were deployed since Monday to release the Whales, with support from local people acting as volunteers.
“They were stranded in shallow waters, only two meters deep. So it was hard for us to release them,” Head of Lampulo PSDKP Basri told The Jakarta Post on Monday.
He explained that the first three Whales had died before being taken back into the sea.
“We released seven of them to the sea this morning, but one of them returned to the beach again, dead. We are still monitoring the other six, making sure they will not strand themselves again,” Basri said.
Along with three ships from the Maritime Affairs and Fisheries Ministry, local fishermen lent their boats to help with the release and monitoring of the Whales, as some of them suffered wounds after hitting rocks on the beach.
Local people had flocked to the beach since Monday to witness the stranded Whales. They took pictures and shared live video via various social media platforms.
Marine and Fisheries Campaign Coordinator for World Wildlife Fund (WWF) Indonesia Aryo Tjiptohandono told the Post that in a lot of cases, beached Whales that have been released will die due to their wounds.
“Crowd control around the area is very important to reduce the stress level of the Whales,” he said.

Indonesia: A Race to Save 10 Stranded Whales
By Christina Caron, 13th November 2017;
Rescuers in Indonesia worked late into Monday night to rescue a pod of Sperm Whales (Physeter macrocephalus) that had become stranded in the shallow waters of an island near the northwest tip of Sumatra in Aceh Province.

Local officials, aided by nonprofits like World Wildlife Fund Indonesia, coordinated a rescue effort using nets, tarpaulins and boats, the group said.
As daylight gave way to darkness on Ujung Kareung beach, the rescuers didn’t give up. As of about midnight local time they were still working, Whale Stranding Indonesia told The New York Times via a Facebook message.
Earlier in the day, the rescuers successfully relocated five of the Whales to deeper water, Nur Mahdi, the head of the Aceh Province marine and fisheries office in Sumatra, told The Associated Press. They are also treating two injured Whales and attempting to refloat the others, he said.
“The team seems to be determined to work during night time to release the remaining Whales,” Whale Stranding Indonesia reported.
Two more Whales were released just before sunrise, the group said, according to an official from the Center for Coastal and Marine Resources Management, the regional marine and fisheries authority in Indonesia.
Time was of the essence in this situation, in part because Whales that come near land are at risk of suffocation and organ failure.
“If you’re 60,000 pounds and your body is meant to float around then gravity can take its toll,” said Regina Asmutis-Silvia, the director of the North American office of Whale and Dolphins Conservation, a nonprofit that has assisted with whale strandings in the United States.
In addition, the shock of being stranded evokes a stress response.
“Elevated levels of adrenaline also take toll on the organs,” Ms. Asmutis-Silvia said. It’s similar to that of a human that has been in a car accident, she added.
It’s unclear why the pod of Whales swam so close to shore. Sperm Whales, which are listed as an endangered species, are the largest of the Toothed Whales. They are not usually found in waters less than 984 feet deep, and prefer areas two times deeper than that, according to the National Oceanic and Atmospheric Administration Fisheries.
In February, more than 650 Pilot Whales (Globicephala melas) became stranded at the northern tip of South Island in New Zealand for reasons that were also unknown, and about 400 of them died. Pathologists hoped to find answers by studying some of the dead animals.
And in April, officials said they were investigating an “alarming” number of Humpback Whale (Megaptera novaeangliae) strandings along the Atlantic coast.
There are multiple reasons these events can happen, Ms. Asmutis-Silvia said, including navigational error, changes in the environment, a wayward hunt for food or tidal changes.
Sperm Whales tend to travel as a group and are unlikely to abandon their podmates.
“When they’re in tight social groups they’re in this together,” Ms. Asmutis-Silvia said.
Whales are especially important to the ecosystem, she said, because their waste fertilizes phytoplankton, the plants that produce half the world’s oxygen.

A herd of 12 wild Sumatran Elephants (Elephas maximus sumatranus) ran amok in a village in Langkat regency, North Sumatra, after failing to rescue an Elephant calf that was trapped in a hole.
Nine coconut trees, eight palm trees, five shacks and a jackfruit tree owned by the local residents of Sumber Waras village, Batang Serangan subdistrict, Langkat regency, were destroyed by the raging Elephants. No one was killed in the incident.
North Sumatra Natural Resources Conservation Agency (BKSDA) Region II conservation head Herbert Aritonang said the Elephants went on a rampage after they witnessed the baby Elephant die in a narrow hole 1.5 meters deep.
For three days, the wild Elephants attempted to rescue the trapped calf, but they instead pushed it deeper into the hole, which likely existed because of a removed stump, he said. “The baby Elephant’s body was pushed down because the soil around the hole fell down and covered half of its body,” Herbert told The Jakarta Post on Thursday.
A joint team of officials from the BKSDA, Mount Leuser National Park and several NGOs found the baby Elephant dead on Sunday. However, the team could not easily recover the corpse because the herd lingered around it, Herbert said.
In order to ensure the safety of the team, they buried the corpse in the hole. “We found the baby Elephant dead with half of its body and four legs buried; only its back and head were visible. So our team covered it with soil to bury it,” Herbert said.
The 12 wild Elephants, comprising two males and several females and baby Elephants, lingered in the village area, which directly borders the national park, several days after the baby Elephant died.
They made loud noises and damaged the area, Herbert said, adding that the joint team had since deployed several personnel to protect the village and the local residents from the Elephants.
The population of Sumatran Elephants, who are a critically endangered species according to the International Union for Conservation of Nature, plummeted to 1,700 in 2014 from 2,400 in 2007, according to data from the Indonesia Elephant Conservation Forum.
Human-wildlife conflict is suspected to be a contributing factor to the population’s decline.
Several months ago, a 12-year old female Elephant was found dead from suspected poisoning near the national park in Barak Gajah village, Sei Lepan subdistrict, Langkat.
Meanwhile, BKSDA spokesperson Alfianto Siregar said the incident marked the first time wild Elephants showed aggressive behavior in the village.
Groups of wild Elephants usually passed by the village once every three months and they never got into conflicts with the residents, who were used to seeing Elephants in the area, he said.
The team’s investigation found no indication that the baby Elephant died from human interference, such as from poison or an Elephant trap, Alfianto said, adding that the calf died purely because it was trapped.
