In the Pacific Northwest, orca sightings are a fairly common occurrence. Still, tourists and locals alike marvel when a pod of "sea pandas" swim by, whipping out their phones to capture some of nature's most beautiful and intelligent creatures in their natural habitat. While orcas aren't a threat to humans, there's a reason they're called "killer whales." To their prey, which includes just about everything that swims except humans, they are terrifying apex predators who hunt in packs and will even coordinate to attack whales several times their own size.

So if you're a human alone on a little platform boat, and a sea lion that a group of orcas was eyeing for lunch jumps onto your boat, you might feel a little wary. Especially when those orcas don't just swim on by, but surround you head-on.

Watch exactly that scenario play out (language warning, if you've got wee ones you don't want f-bombed):


Ummm, yeah. An orca sighting is one thing, but this is a whole other story. Orcas have been known to knock large prey off of icebergs, so the whole "orcas don't hurt humans" thing doesn't feel super reassuring in this scenario.

The footage came from TikTok user @nutabull, whose now-deleted account stated she was from Vancouver Island.

The second video is even more intimidating.

The viral video sparked a debate about whether the sea lion should be kicked off the boat or not. The woman kept telling the sea lion it "had to go" with a frank "Sorry, buddy, that's life," message, though she never actively tried to push it off. Many commenters joked about yeeting the sea lion off the boat to avoid a potentially disastrous encounter with the orcas. Others were on #teamsealion, saying they wouldn't have the heart to boot the poor thing.

The reality is orcas eat sea lions—the circle of life and whatnot. Most of us just don't find ourselves in the middle of that circle, having to figure out whether the apex predators surrounding our boat are going to patiently wait for their lunch to come back or take it upon themselves to bump it back into the water.

Thankfully for the woman, the sea lion seemed to decide on its own that its options were limited and dove back in to take its chances with the orcas. But phew, that encounter would be harrowing for just about anyone.

Best of luck, sea lion. Hope you're an exceptional swimmer.

Efforts to release marine mammals back into the wild are proving successful.

Dolphins are one of the most intelligent creatures on Earth, capable of more complex communication and comprehension than nearly every other species. Their intelligence is one reason humans have captured dolphins and trained them for entertainment, but it's also one reason why keeping them in captivity is seen as cruel.

According to The Korea Times, Bibong, a 23-year-old Indo-Pacific bottlenose dolphin, has just been successfully released into the wild after 17 years of captivity in an aquarium in South Korea. He is the last of his species to be freed by the Korean government after being declared endangered in 2012.

The plans for Bibong's release were announced in August and Bibong has spent more than two months training to adapt to life in the wide open ocean. Bibong is one of eight dolphins that had been kept in an aquarium on Jeju Island, but the other seven were released in 2013, 2015 and 2017. According to Korea Now, Bibong was seen refusing to obey his trainer's orders during a performance last year, "possibly due to chronic stress and pressure."


This summer, Bibong was moved to a transitional facility where he could learn to communicate with other dolphins and prepare for life in the wild. An estimated 120 Indo-Pacific dolphins live off of Jeju Island, where Bibong was originally captured in 2005.

Now that he's been released, he will be monitored by the Ministry of Oceans and Fisheries daily for 30 days via a tracking device attached to his fin, followed by at least five consecutive days of monitoring per month for another six months. Updates on his progress will be provided to animal rights groups, marine mammal experts and government officials, according to the Times.

Both The Korea Times and Korea Now note that a popular Netflix show, "Extraordinary Attorney Woo," helped bring the plight of the Indo-Pacific bottlenose dolphin into the spotlight when the show's lead character said, "I want to see an Indo-Pacific bottlenose dolphin near the coast of Jeju someday."

In August, Korea Now shared footage of Bibong as he was moved from the aquarium to the training facility where he has spent 70 days preparing for life in the wild:

Oceans Minister Cho Seung-hwan told The Korea Times that the most important thing for the dolphin is to live a healthy and happy life after it returns to the ocean.

"We will fortify marine animal protection policies to improve their well-being," Seung-hwan said. "The government will continue discussions with the aquarium industry to help a greater number of animals return to where they came from and belong."

The ministry is also hoping to release a beluga whale named Ruby from an aquarium in South Jeolla Province sometime late next year.

Efforts to save marine mammals from extinction have shown great potential for success. Humpback whales, for example, have made a comeback and have been taken off of endangered species lists after industrial whaling nearly wiped them out in the 20th century.

But even whales and dolphins that aren't in danger of extinction deserve to live freely in the wild whenever possible.

Watching sea cucumbers eat is wild.

Nature is full of wonders, from the breathtakingly beautiful to the truly terrifying. (Ever seen an anglerfish? Yikes.) But some wonders come from the most unexpected places.

For instance, the unassuming sea cucumber.

If you've ever seen a sea cucumber, you know they're not terribly exciting. I'd bet $1,000 that if you were to ask 1,000 people what animal they wish they could be, none of them would say "sea cucumber." They don't fly, they don't really swim, they don't make funny noises and they're not particularly cute. The name "cucumber" should be a clue that they basically just sit there like vegetables, a background feature adding a little shape and color to the underwater landscape. They don't even have a brain. They're just kind of there.

Or at least that's what I thought before I saw one eat.


Because pretty much all these creatures do is eat and poop, something about one of those things had to be interesting, right? As it turns out, the way sea cucumbers eat is flippin' fascinating, if not slightly nightmarish.

When it's dinner time, the cucumber opens up its mouth and extends a network of tendrils attached to "feet" out into the surrounding water. These tendrils act as hands, grabbing the plankton, algae and other tiny things in the water, and then the feet shove that organic matter into the sea cucumber's pie hole.

That sounds all well and good on paper, but it's a whole other thing to actually see it in action. I had no idea what I was in for when this video started, and now I'll never be the same.

Gaaaahhhhh. Whyyyyy? Why is it so cool and so disturbing at the same time? Why do sea cucumbers suddenly turn into strangely beautiful horror movie creatures when they get the munchies?

As it turns out, sea cucumbers really aren't as boring as they seem. They also breathe through their bums and let little fish live inside their anuses, so that's neat. Also, when they feel threatened, they literally shoot their own guts out of their butts.

Three cheers for the surprisingly bizarre sea cucumber for reminding us that there's always much more to nature than meets the eye.

Manatees, aka "sea cows," are starving to death in Florida so officials are staging an intervention.

Manatees are one of Earth's more oddly beloved creatures. They're cute in a "so ugly they're cute" kind of way, and their bulbous, slowly meandering bodies have earned them the nickname "sea cows." They are a migratory species, and in the U.S. they congregate mainly in the waters of Florida.

Sadly, manatees are also dying at an alarming rate after only being taken off the endangered species list in 2017. During the first nine months of 2021, nearly 10% of Florida's manatee population died—more than double the five-year average. Many of those deaths were due to water quality issues impacting the growth of seagrass, one of the manatee's primary food sources.

Boat strikes, habitat loss and toxic algae blooms also threaten the species, but far too many are dying of simple starvation. According to WUSF, at least 58% of the seagrass in the northern Indian River Lagoon has been lost since 2009, and at least 96% of the Banana River's seagrass is gone. Both river habitats have long served as winter homes for manatees.


To help stave off starvation, officials with the Florida Fish and Wildlife Conservation Commission (FWC) have staged a salad intervention of sorts. CNN reports that around 350 manatees are currently coming to a temporary field response station in Cape Canaveral to get their daily servings of romaine and butter lettuce. Since the feeding program started, it has served between 25 and 800 manatees a day.

The sea cows salad bar serves up 3,000 pounds of lettuce a day, and officials say it's helping.

"At this point in time, we have been successful. Manatees are eating the romaine," Ron Mezich of the FWC told CNN. "We are exposing [a] large amount of animals to this food source and we are making a difference." The lettuce has nutrients and digestible carbohydrates the sea cows need, he said.

The program has been funded largely through donations from the public and is slated to continue through March.

Hopefully, the FWC will see improvement in the manatee mortality numbers as a result of its efforts. As of February 11, there have already been 261 manatee deaths in the state, though most are still awaiting necropsies to determine the cause of death.

Everyone can take part in helping these gentle giants have a healthy future by following guidance for wise use of waterways, supporting legislation for wildlife protection, reducing and cleaning up pollution along beaches and waterways and encouraging leaders to take meaningful action on climate change.

Don't try to throw your own salad in the ocean to feed the manatees, though. Officials recommend leaving the lettuce to experts.
