Orcas are most terrifying animals when you know what they are capable of.
I have only scanned through the article but have not found how they attached the cameras.
I wonder how did they do that.

- neuronic 6y agoIf Free Willy is any indication they waited until an Orca jumped above them and quickly attached a camera to its belly. To make my comment more productive, maybe they attach it to the fins using sticks and bait, like with sharks: https://phys.org/news/2016-06-camera-tag-white-sharks.html https://phys.org/news/2016-06-camera-tag-white-sharks.html
- m463 6y agoLet's just say Johah sort of fell into this line of research.
- alejo 6y ago"It’s tricky work. Finding the orcas is the first problem. Getting a tag on a wild orca is the next one. It takes strength and dexterity to extend a 25-foot-long carbon-fiber pole from a bouncing skiff to tap the 2-pound tag onto a swimming killer whale, aiming for the area right below the dorsal fin. So far the team has been able to tag two southern residents, L87 and L88, and nine northern residents."

- AlbertoGP 6y agoMore details in this post they made in Facebook the 28th of August: > It takes a lot of skill and expertise to place a suction-cupped data-logger onto a killer whale. > The most difficult part of tagging a whale is piloting the vessel into the proper position next to the whales. Fortunately, we have a skipper with years of whale-watching experience to safely navigate near them. He starts each approach by analysing the behaviour of the whales to establish their swimming speed and heading. He will then parallel them and gently slide towards an individual until we are at just the right distance. Any harassment or sudden movements on our part, would cause the whale to avoid us. They are very aware of our presence and behaviour ---- they just don’t know our intent. > Polarized sunglasses helps the tagger standing in the pulpit at the front of the Steller Quest to see the whales underwater. As he senses that the whale is coming to the surface to breathe, he will lower a very long pole (25.5 ft, ~8 m) and place the tag near the dorsal fin. > The carbon fiber pole holding the tag only weighs about 10 lbs (4.5 kg), and the tag is about 2 lbs (0.9 kg). However as the pole is lowered to a horizontal position, the weight of this 2-lb tag (as felt by the tagger at the pivot point of the pole) increases to about 100 lbs (45 kg). The tagger’s front arm on the pole feels it is lifting 100 lbs, while his back arm pushes down against 100 lbs of force to counter balance the pole. It takes incredible strength and skill. > All four suction cups need to be pushed firmly against the whale. To a person, it would feel like being pushed or shoved as the suction cups are pushed flat. However, to a 3,000 kg (~6,500 lb) killer whale, it appears to be a relatively soft touch. Some killer whales shudder briefly when touched, while others show no reaction. However, all of the whales we have tagged continue about their business seemingly unaware of the hitchhiker they just picked up. To a killer whale, the weight of the tag is like the weight of a wedding ring worn by a person. https://www.facebook.com/marinemammal/posts/3426676784050634 https://www.facebook.com/marinemammal/posts/3426676784050634
- jnellis 6y agoI used to work a chartered fishing boat with my father out of Blaine and we'd often get orcas swimming alongside us so close that you could reach out and pet them, which some customers did. They are very curious.
- coldcode 6y agoOrcas are terrifying to sea creatures, but oddly enough are not interested in humans.
- CrLf 6y agoThey’ve been attacking boats in the Gibraltar region recently, though.
- nicoburns 6y agoThe relationship is also largely reciprocal. Humans are terrifying land creatures, but don't often attack Orcas.

- BurningFrog 6y agoOrcas knows what food they like. We're not on the list.
- ceejayoz 6y agoThere are interesting stories of human/orca cooperation, even. This one even comes with photographic and physical evidence: https://en.wikipedia.org/wiki/Killer_whales_of_Eden,_New_South_Wales https://en.wikipedia.org/wiki/Killer_whales_of_Eden,_New_Sou...

- Jaruzel 6y ago> Orcas are most terrifying animals when you know what they are capable of. They are not [erroneously] called 'Killer Whales' for nothing.
- JackFr 6y agoWhat is “erroneous” about referring to them as killer whales?
- Jaruzel 6y agoBecause Orcas are not whales, they are dolphins.
- JackFr 6y agoFrom Wikipedia: “The killer whale or orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. The toothed whales are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales.“ So, yes, in the sense that sperm whales and porpoises are also dolphins, it too is a dolphin. but that’s not typically how we use the word dolphin.
- thaumasiotes 6y agoI think it's normal to consider that porpoises are dolphins. Sperm whales, not so much.
- dwaltrip 6y agoI’m not sure if this settles the debate, but sperm whales and porpoises are in a different (super?) family than dolphins and killer whales. https://en.m.wikipedia.org/wiki/Physeteroidea https://en.m.wikipedia.org/wiki/Physeteroidea https://en.m.wikipedia.org/wiki/Delphinoidea https://en.m.wikipedia.org/wiki/Delphinoidea
- arunix 6y ago> toothed whales are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth The article for whales [1] linked from that sentence says "They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises."

- Kiro 6y agoSwimming with wild orcas is a popular activity in Norway where you get as close as an arm length from them while they circle you.
- sidibe 6y agoAre you sure you're talking about orcas, I'd think there'd be videos of that? Seems crazy. I've only seen one video of a lady swimming with orcas but she was very familiar with them
- yashap 6y agoI just searched for “Norway swimming with orcas” on YouTube, and surprisingly a lot of adventure-tourism type videos showed up.
- Kiro 6y agoI'm on my phone but there should be a lot on YouTube. Here's one such company: https://www.orcanorway.info/services/snorkeling-with-orcas https://www.orcanorway.info/services/snorkeling-with-orcas No prior experience or training needed so not just for professionals. You just jump in with pretty basic snorkeling equipment.
- ironmagma 6y agoAre they more terrifying than humans? We are capable of a lot more, for better or worse.
- mbrameld 6y agoIn the post you're replying to, most is an adverb modifying terrifying meaning "to a very great degree". It isn't saying they're THE most terrifying. It's another way of saying they're very terrifying.
- throwawaysea 6y agoThey are capable animals, but I think they aren't terrifying to humans because they seem intelligent/sentient and display group social dynamics that are similar to our own. There are also no records of orcas attacking humans in the wild. Most encounters look like this: https://youtu.be/Vaq4pHxM5P4 https://youtu.be/Vaq4pHxM5P4
- ironmagma 6y agoThere are records of orca attacks on humans, just not deaths.
