Humpback whale washes ashore in Long Beach Township
LONG BEACH TOWNSHIP — A dead humpback whale washed ashore at the 130th Street beach in the Beach Haven Terrace section on Friday morning, according to the Marine Mammal Stranding Center in Brigantine. The stranding center's stranding coordinator responded to the scene about 7 a.m. and the 'heavily decomposed' remains were moved to the municipal Department of Public Works yard to be examined by staff from the center, according to a statement from the center.

The carcass was in the advanced stages of decomposition and therefore no longer viable for further biological sampling. Based on photographs, this whale was identified as the same whale that was first observed deceased and floating approximately 3½ miles off of Harvey Cedars on Monday. As disposal of a whale carcass is the responsibility of the property owner, which is Long Beach Township, and officials opted to bury the remains at the public works yard on Long Beach Boulevard in Beach Haven Terrace. In addition to the Public Works Department, the Long Beach Township Police Department, its municipal Beach Patrol, the New Jersey Department of Fish and Wildlife, and the National Oceanic and Atmospheric Administration Office of Law Enforcement, all provided assistance at the scene.

Orcas filmed making out in the wild for first time
When you buy through links on our articles, Future and its syndication partners may earn a commission. For the first time ever, a pair of orcas have been spotted making out in the wild. The amorous pair was observed nibbling each other's tongues during a snorkeling expedition in the Kvænangen fjords in northern Norway, around 68 miles (109 kilometers) northeast of Tromsø, according to a new study published June 11 in the journal Oceans. This tongue-nibbling behavior has only previously been seen on a handful of occasions in captivity. The action, described as resembling "kissing" by the citizen scientists who observed it, may play a role in social bonding, the researchers suggest. The citizen scientists spotted and recorded this unique behavior during a whale-watching snorkeling expedition in October 2024. The interaction lasted just under two minutes and involved three bouts of gentle mouth-to-mouth contact between the two orcas (Orcinus orca). Afterward, the pair swam their separate ways. Tongue-nibbling was first seen in captive orcas in 1978 and was described again in 2019 at Loro Parque, a zoo in Tenerife, Spain that houses three captive orcas. The researchers spoke to a range of divers and other orca researchers regarding the behavior in the wild, but only a handful had ever spotted it. Trainers at Loro Parque noted that four individuals at the facility had been seen tongue-nibbling, but the orcas had not performed the behavior for several years. "Tongue-nibbling is exceptionally rare," study co-author Javier Almunia, a marine mammal researcher and director of Loro Parque Fundación, told Live Science via email. "Orca caretakers at several facilities are aware of the behaviour, but its prevalence is extremely low — it may appear and then not be observed again for several years." Mouth contact between animals is seen in a vast number of species and can represent a variety of different social cues. Many social animals use mouth contact to reinforce bonds, such as primates, who engage in kissing or lip-touching as a sign of trust and friendship. In dogs and wolves, mouth licking, especially from younger or subordinate individuals, can represent a sign of respect or submission to a higher-ranking individual. The researchers suggest that tongue-nibbling in orcas may be a form of social bonding, similar to that seen in belugas (Delphinapterus leucas), a type of toothed whale. "Tongue-nibbling itself has not been recorded in other species, but comparable mouth-related social interactions have been observed in belugas (e.g., mouth-to-mouth contact). This could suggest that, given cetacean anatomy — particularly the adaptation of limbs to the marine environment — oral contact may serve as a more versatile means of social communication than in terrestrial mammals," Almunia said. "This behaviour appears to serve affiliative purposes and may play a role in reinforcing social bonds or resolving conflicts, akin to grooming or reconciliation behaviours in other highly social species," he added. However, we cannot be certain of what exactly drove the orcas to exhibit this behavior without further research. "We can only speculate on the function and nobody can know for sure without data relating it to known social structures in the wild (in captivity the 'social structure' is completely artificial and therefore largely irrelevant for understanding social function in evolutionary terms)," said Luke Rendall, a marine mammal researcher at the University of St. Andrews in Scotland. "It may be affiliative, it might be a form of begging, that is trying to stimulate food transfers, it might even be a form of grooming, somehow having a cleaning function," Rendall told Live Science. The researchers suggest in the paper that the observed tongue-nibbling could be a "trend" play behavior in the orcas, similar to positioning dead fish on their heads as hats, which was seen in one orca population. This observation of tongue-nibbling in the wild suggests that the behavior is not exclusive to captive animals and instead is found in a range of genetically distinct populations. "Observing the same behaviour in wild orcas confirms that this is a natural behaviour retained in orcas under human care. This continuity supports the idea that behavioural studies in zoological settings provide important insights into the ethology of wild populations," Almunia said.

"There's no quantification here — no attempt to calculate actual rates by doing the hard work of pulling together numbers such as the number of hours observed in the wild per observation of this behaviour, and the same for captivity," Rendall said. "Even if the behaviour itself is fascinating, and I think it is, we are limited on conclusions because it's just one observation, but it is telling that in their summing up these authors take great pains to try and explain how this observation justifies the activities of [orca captivity and swim-with-cetaceans programmes]. It does not, in my view."

Orcas Use Kelp as a Possible Grooming Tool
A hundred feet or more above the Salish Sea — high enough to avoid spooking any marine mammals below — a drone camera recorded orcas periodically pairing up to perform a sort of swimming, rolling hug. That was nothing new for the Southern Residents, a group of orcas in the Pacific Northwest that lives south of other groups. But when researchers inspected the drone videos, which were filmed last year, they noticed something they had not seen before: A little piece of kelp was often sandwiched between the creatures' bodies. The research, published this week in the journal Current Biology, is among the most compelling evidence yet that marine mammals make and use tools, a skill more commonly attributed to terrestrial animals like monkeys, humans and crows. Michael Weiss, an author of the study who is the research director for the Center for Whale Research in Washington State, said that the Southern Residents had long used their intelligence and social skills to adapt to a challenging environment. The group of 73 orcas, which are often called killer whales, has been shrinking for decades and was listed as endangered in 2005. 'I'm not surprised that we eventually found tool use in killer whales,' Dr. Weiss said. 'But it was obviously a surprise to see this particular behavior, because we just had no idea it was happening.' Kelp is not that hard to find in the waters near British Columbia and Washington State, where these orcas generally stay. But they were not just grabbing any old floating stalk. They were using their teeth to break off pieces, which were almost always about two feet long. Want all of The Times? Subscribe.

Thousands of whales join the ‘humpback highway' along Australia's coast
Humpback whales undertake one of the world's longest mammal migrations, travelling from Antarctic feeding grounds to breeding areas off Australia 's coast during winter. This annual migration, involving approximately 40,000 whales, creates the "humpback highway" along Australia 's east coast, leading to frequent sightings near urban centres like Sydney. The whales' large size and tendency to stay close to shore make them highly visible, sometimes causing extraordinary events like halting ferry traffic in Sydney Harbour due to their curious nature. The humpback population has significantly recovered since becoming a protected species in 1963, leading to increased interactions with humans. While offering unique viewing opportunities, the growing whale population and human proximity raise concerns about entanglements, collisions, and potential changes to migratory patterns due to climate change and krill harvesting.
