Rescue team disentangles whale

April 23 2015 at 10:46am

A WHALE has been rescued near Oyster Bay in the Eastern Cape after it was entangled in rope.

South African Whale Disentanglement Network (SAWDN) spokesman Craig Lambinon said that the incident happened on Tuesday afternoon.

Oyster Bay is located between Humansdorp and St Francis Bay on the east coast.

“At 4.40pm on Tuesday, the network was activated to approximately one nautical mile offshore of Oyster Bay on reports from Nick Bournman, from the Oyster Bay Beach Lodge, of a whale appearing to be entangled in rope and buoys,” said Lambinon.

“The NSRI St Francis Bay sea rescue craft Spirit of St Francis II responded, carrying trained volunteer members of the network.

“On arrival on the scene at 5.15pm, two humpback whales were located swimming together, possibly a mother and child, and the smaller of the two whales was the one entangled in rope and three floatation buoys, with the rope entangled around the peduncle.”

Lambinon explained that an extensive operation then took place to release the whale using specialised disentanglement equipment.

“In an operation, lasting just under 30 minutes, all rope and floatation buoys were successfully removed from the whale and recovered,” |he said.

“The whale appears to not be injured from the ordeal and appeared to be swimming confidently following the disentanglement, and SAWDN is confident that the operation has been successful.”

Pippa Middleton admits eating whale meat in newspaper column

Pippa Middleton has recieved criticism from conservationists across the world for eating whale meat on a trip to Norway, which she recounted in her column for the Daily Telegraph.

In the piece she said: ”We dined on smoked whale carpaccio (which tastes similar to smoked salmon but looks more like venison carpaccio).”

Despite strong international pressure and commercial whaling being banned since 1986 Norway is still one of three countries (the other two are Japan, and Iceland) that still allows whaling and in 2014 had a record year when more than 700 were killed.

“This is really disappointing news, particularly as Pippa is so high-profile, and given how active her brother-in-law, William [Duke of Cambridge], is on speaking out against poaching and wildlife crime. Commercial whale hunting is banned, the UK government backs the ban and for good reason. Killing whales is cruel, there is no humane way to kill them and many are slaughtered using brutal harpoon grenades. Last season, 731 minke whales suffered an agonising death at the hand of Norwegian whalers.”

Pippa does not say what type whale meat she ate but the most likely one is minke, the second smallest baleen whale.

Philip Mansbridge, UK Director of IFAW, said: “It’s likely that Pippa Middleton wasn’t aware of the horrific suffering caused by commercial whaling nor the devastating damage that it causes to whale populations.  By eating whale meat, she is unwittingly setting a bad example that may encourage other tourists to do likewise. We would hope she acknowledges her mistake and will promote whale watching true to the slogan: meet us, don’t eat us.”

From Celebitchy.com:

“Pippa is not known for common sense or compassion, but it still beggars belief that anyone, let alone someone from a country like ours, where whale meat has long been banned, could be oblivious to the uproar over Norway’s slaughter of these gentle giants,” Elisa Allen, associate director of People for the Ethical Treatment of Animals U.K., said Thursday in an exclusive statement to E! News. “Does she think or read? What’s next, a panda steak or an elephant canapé? These whales are harpooned and bled to death before they’re gutted. If Pippa is looking for a culinary experience, some of the best high-end vegan food—recently named by Forbes magazine as a top food trend—can be found in Norway, and it’s good for the heart, an organ Pippa seems to lack.”

Russian gray whale Varvara, longest mammal migration

Longest mammal migration ever recorded measures in at 14,000 miles

April 16, 2015

And the remarkable journey is raising questions about the status of a critically endangered whale species.

In a study using satellite-monitored tags to track three western gray whales, a team of U.S. and Russian researchers recorded a stunning round-trip trek of 14,000 miles. The trio traveled from their primary feeding ground off of Sakhalin Island in Russia across the Pacific Ocean and down the west coast of California to Baja, Mexico and back home again.

One of the whales, dubbed Varvara by the scientists, visited the three major breeding areas for eastern gray whales, which are found off North America.

For a long time it was believed that western gray whales had gone extinct, but a small group was discovered in Russia off Sakhalin Island; they now number around 150 individuals and have been monitored by scientists from Russia and the U.S. since the 1990s. Meanwhile, populations of eastern gray whales were also in a tight spot, but conservation efforts have brought them back – today they are believed to have a population of some 18,000.

But here’s why Varvara’s visit to the eastern gray whales is interesting. Not all experts believe that the two species are in fact distinct, separate species. A number of scientists have proposed that western and eastern gray whale populations are not isolated and that the gray whales found in Russian waters are a part of an eastern population that is restoring its former range.

“The fact that endangered western gray whales have such a long range and interact with eastern gray whales was a surprise and leaves a lot of questions up in the air,” said Bruce Mate, director of the Marine Mammal Institute at Oregon State University and lead author on the study. “Past studies have indicated genetic differentiation between the species, but this suggests we may need to take a closer look.”

“The ability of the whales to navigate across open water over tremendously long distances is impressive and suggests that some western gray whales might actually be eastern grays,” Mate said. “But that doesn’t mean that there may not be some true western gray whales remaining.

He adds, “If so, then the number of true western gray whales is even smaller than we previously thought.”

Does this spell doom for the western whales? Protecting them has proven challenging. Five western grays have perished in Japanese fishing nets within the last 10 years and their feeding grounds off Japan and Russia include fishing areas, shipping corridors, and oil and gas production – as well as future sites oil sites. But with this new research, hopefully fresh data and visibility will inspire some momentum in conservation efforts. With so few of these wandering giants left, and maybe even fewer than we thought, the time is now.

Otago research details 40 million-year-old family tree of baleen whales

New University of Otago research is providing the most comprehensive picture of the evolutionary history of baleen whales, which are not only the largest animals ever to live on earth, but also among the most unusual.

Most other mammals feed on plants or grab a single prey animal at a time, but baleen whales are famous for their gigantic mouths and their ability to gulp and filter an enormous volume of water and food.

In a paper appearing in the UK journal Royal Society Open Science, Otago Geology PhD graduate Dr Felix Marx and Professor Ewan Fordyce present a comprehensive family tree of living and extinct baleen whales stretching back nearly 40 million years.

The pair says that similar family trees have been constructed before, but theirs is by far the largest and, crucially, the first to be directly calibrated using many dated fossils.

The research shows which whales are related and exactly how long ago every branch of the tree—whether extinct or still alive—first arose.

This new family tree allows the researchers to estimate: (1) how many species of baleen whale have existed, (2) similarities and differences between different lineages in terms of overall body shape, and (3) how fast baleen whales evolved at any chosen time over the last 40 million years.

“We find that the earliest baleen whales underwent an adaptive radiation, or sudden ‘evolutionary burst’, similar to that of ‘Darwin’s finches’ on the Galapagos Islands,” says Professor Fordyce.

Dr Marx adds that this early phase of whale evolution coincided with a period of global cooling. At the same time, the Southern Ocean opened, and gave rise to a strong, circum-Antarctic current that today provides many of the nutrients sustaining the modern global ocean.

The researchers found that during their early history, whales branched out into many different lineages, each with a unique body shape and feeding strategy.

“Rather surprisingly, many of these early whales were quite unlike their modern descendants: Although some had baleen, others had well-developed teeth and actively hunted for much bigger prey than is taken by modern species,” says Professor Fordyce.

Yet, after a few million years of co-existence, the toothed ‘baleen’ whales disappeared, leaving behind only their filter-feeding cousins, he says.

That extinction occurred between 30 and 23 million years ago and was about the time that the circum-Antarctic current reached its full strength, providing more nutrients that made filter feeding a more viable option.

The researchers say that the toothed ‘baleen’ whales disappeared perhaps because of increasing competition from other newly evolved toothed marine mammals, such as dolphins and seals.

They found that filter-feeding whales remained successful and diverse until about 3 million years ago, when the number of lineages suddenly crashed.

“This decline was driven mainly by the disappearance of small species of baleen whale, which left behind only the giants—ranging from 6 to as much as 30 metres—that plough the ocean today,” says Dr Marx.

He says the disappearance of small whales likely resulted from the onset of the ice ages, which altered the distribution of available food, caused shallow water habitats to shift or sometimes disappear, and created a need for long-distance migration between polar feeding grounds and equatorial breeding grounds.

“This behaviour—long distance-migration—is still one of the hallmarks of all baleen whales alive today,” notes Professor Fordyce.

Local resident discovers whale fossil in Ha Tinh

A large piece of a whale‘s fossilised vertebra has just been found in the central province of Ha Tinh.

The fossil, measuring 37cm by 35cm by 80cm and weighing 19kg, was discovered accidentally at Thach Khe metal mine, 1km from Thach Hai Beach, by a local person named Duong Dinh Canh.

Director of Ha Tinh Museum Nguyen Tri Son and Australian archaeologist Philip Palmer examined the fossil and determined it was part of a whale‘s vertebral column. But they cannot determine the exact age of the fossil till some more research is done.

The experts will soon transport the fossil to the provincial museum for further study and exhibition.

Gray whale spring migration

Gray whales make their annual return, though a bit late

By Sharon Salyer

Gray whales have been spotted near Whidbey and Camano islands, part of their annual spring layover on their way from Mexico to Alaska. You don’t necessarily have to board a boat to see their heart-shaped spouts and their V-shaped flukes. They can be spotted from shoreline areas in Snohomish County and from spots such as Cama Beach State Park on Camano Island and Ebey’s Landing beach and bluffs on Whidbey Island, according to the Orca Network.

The whales’ return was just a tad off schedule this year, said John Calambokidis, a research biologist for Cascadia Research, an Olympia-based nonprofit which studies marine mammals. “We were just a little nervous that some didn’t show up,” he said. A group of about 10 whales can sometimes stop over in the Whidbey and Camano island areas in mid-February or early March. “The earliest we had one of these whales was the first weekend in March,” he said, with more arriving by mid-March.The core group sometimes is joined by other whales intermittently, he said.

“This is just some sort of in-between pit stop for them,” Calambokidis said. “They’ll often be here for several months. ”The stop is off their migration route, which continues north, he said. The ones that stop have learned that there’s something good to eat here — ghost shrimp. Susan Berta, co-founder of the Orca Network and the Langley Whale Center, said the whales usually remain in the area through May. About six whales have been seen so far, she said. Sightings often are reported in Possession Sound, Saratoga Passage and offshore areas of Island and Snohomish counties, she said.

A bell rings in one of Langley’s parks when whales are spotted. The town hosts an annual Whales Festival, scheduled this year for April 18 and 19. The same group of 10 to 12 whales makes an annual local stop on their migration route from Baja, Mexico, then continues their trek north to the Bering Sea, she said. There’s never been a confirmed sighting of a calf during the time the whales make their local stop, Calambokidis said. They’re predominately males, but three females have been identified in the group. The females “tend to have little more spotty history of showing up here,” he said. “We suspect that may be because in the years they have calves, they don’t make this stop.

”One gray whale seemed to accidentally discover the marine feast of the local ghost shrimp feeding grounds, he said. “He wandered around Puget Sound for a while in the early 1990s before discovering how rich the areas around Island County are for ghost shrimp. “Now he comes back directly to that spot,” Calambokidis said.Cascadia Research plans on doing some study later this month on what proportion of the whales’ total diet while they’re here is ghost shrimp, particularly in the intertidal areas where people harvest the shrimp for bait.The nonprofit is working with the state Department of Natural Resources to investigate how much competition there is between the needs of the gray whales for the shrimp and people’s harvest of the shrimp, he said. Gray whales are thought to live up to 50 years and weigh about 20,000 pounds.
