Researchers baffled by the whale's mysterious behavior

For years, scientists have been baffled by the whale's mysterious behavior. Why do they keep swimming in circles?

Some experts believe that the whales are swimming in circles as a way of communicating with one another. Others believe that they are doing it as a way of finding their way back to their pod.

While scientists have yet to agree on what is causing the whales to swim in circles, they all seem to agree that it is an interesting phenomenon worth studying.

California fishermen spot a humpback whale for first time in years

After a five-year absence, a humpback whale has been spotted by California fishermen. The sighting occurred about five miles off the coast of Dana Point.

Karl Hildebrandt, one of the fishermen who witnessed the whale, said he was "pretty stoked" to see it. "I was speechless," he said. "It was pretty amazing."

It's unclear why the humpback whale has been absent from California's waters for so long, but researchers are excited to have another opportunity to study it. "We don't know where it's been or what it's been doing," said Kristen semi, research associate with the Cascadia Research Collective in Olympia, Washington.

Semi and her team are planning to study the whale's movements and behavior now that it has been sighted again. This information could help them understand why the whale disappeared for so long and what caused it to come back.

Humpback whales are usually found in colder waters near Alaska and Canada, but they sometimes migrate south to warmer climates during winter months. It's unclear why this particular whale has stayed in California's waters for so long, but researchers are hopeful they will be able to learn more about its behavior.

Humpback whale breaches near boatload of tourists

A group of tourists in Monterey Bay got a close-up view of a humpback whale breaching on Saturday.

The whale came up out of the water about 50 yards from the boat, and breached two more times before swimming away.

"It was pretty amazing," said Cynthia Martinez, one of the tourists on the boat. "We were just taking pictures and video and enjoying the show."

Humpback whales usually migrate north to Alaska in the summer, but this one appears to have stayed behind in California.

Whale watchers joy as huge pod of orcas spotted near Vancouver

For whale watchers and marine enthusiasts near Vancouver, yesterday was a day of delight. A pod of up to 50 orcas was spotted by boaters and kayakers near the mouth of the Fraser River.

"It was an amazing experience," said local resident Bill Meller. "We saw at least six or seven orcas, including a couple of calves. They were so close, you could see the individual markings on their bodies."

The pod was first spotted by ferry passengers travelling from Tsawwassen to Swartz Bay. Word quickly spread, and before long people were paddling out in kayaks and zooming around in boats to get a closer look.

The orcas were eventually sighted as far east as White Rock, providing plenty of opportunity for spectators to snap photos and videos of the majestic creatures.

For many, it was a once-in-a-lifetime experience. "I've been whale watching all over the world, but I've never seen anything like this," said Meller.

Whale watchers in the area can usually expect to see transient orcas (those that live near the coast) between March and October, but sightings are not always guaranteed.

So residents and visitors alike were thrilled when this large pod made an appearance just in time for summer tourists.

50 stranded whales die in Bangladesh

A recent discovery of 50 dead whales in Bangladesh has baffled local officials and conservationists alike. The mass beaching of the whales, which belong to a critically endangered species, has raised concerns about the health of the world's oceans.

The huge creatures were found on the banks of Dhaka's main river, the Buriganga, early on Wednesday morning. Locals alerted authorities after seeing the whales struggling in the water before they eventually died.

Officials say that it is still unclear why the whales came ashore and died. Some have speculated that they may have been poisoned by pollutants in the river, while others believe they may have been affected by an oil spill.

Environmentalists have expressed concern over the event, warning that it could be a sign of things to come for the world's marine life. The Buriganga is one of Bangladesh's most polluted rivers, and its waters are known to be heavily contaminated with industrial waste and effluent from nearby factories.

This is not the first time that whales have beached themselves in large numbers in Bangladesh. In 2014, around 100 whales washed up on the coast near Chittagong, some 200 kilometers away from Dhaka.
