Over in [this thread](http://boards.straightdope.com/sdmb/showthread.php?t=582444) about Heinlein, a weird discussion broke out about dolphins. Granted, it’s a random hodgepodge of a thread wandering around the topic rather wildly. Nevertheless, the dolphin discussion seems just a bit far afield even for that. So I decided to start a new thread. Apologies for the cumbersomeness, but I’m dragging over previous comments to get the conversation in one place. Multiquote for some reason didn’t carry over, so manually quoted. * * * [QUOTE=MIchelleRose] [QUOTE=Amateur Barbarian] I’d bet he meant dolphins, whales, great apes and elephants. Unless he was ‘making strange’ and we’ve all missed a reference to khauga let loose on earth. [/QUOTE] You are correct, sir, although rather off-target regarding my gender. Dolphins, whales, great apes and elephants can all recognize themselves in a mirror. So can octopi. Chimps too, although they are so closely related to us, their sentience is unsurprising. Sentience is a function of self-awareness and awareness of other species. With the exception of the great apes–and any other primate species–all the creatures I cited have brains larger than humans. I might also point out that, in all the many years mankind has interacted with dolphins (porpoises, actually), there has never been even _one_ verified attack on a human by a porpoise. That alone should tell us something. [/QUOTE] [QUOTE=BrainGlutton] That is not true. At least, not WRT dolphins, don’t know about porpoises. [/QUOTE] [QUOTE=MIchelleRose] I stand corrected. _One_ incident. On the other hand, if a bunch of people were trying to jam sticks up _your_ nose, wouldn’t you be a little irritable? All the other damages can be attributed to excessive playfulness and a porpoise’s innate practical joker mentality. They like to play tricks, both on humans and each other. That’s another sign of a highly intelligent species: a well-developed sense of humor. Orcas are _not_ friendly and should _never_ be considered as such, even though they are at least as intelligent as porpoises. They are the “wolves of the sea” and anyone with half a brain will put lots of distance between themselves and two and a half tons of sentient carnivore. Definitions: dolphins are fish, _coryphaenidae_, like the pompano. Porpoises are the mammals we know as bottlenose dolphins. The two terms are often mixed, much to the grief of marine biologists. I know a couple and they always frown when I use the term “dolphin” to describe _tursiops truncatus_. Bad form, doncha know. [/QUOTE] [QUOTE=Irishman] > [@MIchelleRose](#): > > I might also point out that, in all the many years mankind has interacted with dolphins (porpoises, actually), This is [false](http://en.wikipedia.org/wiki/Dolphin). > [@](#): > > The term ‘dolphin’ can be used to refer to, under the suborder Odontoceti, all the species in the family Delphinidae (marine dolphins including orcas and pilot whales) and the river dolphin families Iniidae (South American river dolphins), Pontoporiidae (La Plata dolphin), Lipotidae (Yangtze river dolphin) and Platanistidae (Ganges river dolphin and Indus river dolphin).[7][8] This term has often been misused in the US, mainly in the fishing industry, where all small cetaceans (dolphins and porpoises) are considered porpoises, while the fish dorado is called dolphin fish.[9] [snip] Killer whales also belong to the family Delphinidae and therefore qualify as dolphins. Though the terms ‘dolphin’ and ‘porpoise’ are sometimes used interchangeably, **porpoises are not considered dolphins** and have different physical features such as a shorter beak and spade-shaped teeth; they also differ in their behavior. **Porpoises belong to the family Phocoenidae** and share a common ancestry with the Delphinidae.[12] Bolding and underlining added for emphasis. Dolphins are not porpoises. Porpoises are not dolphins. Dolphins are not finned fish, but there are fish that are called “dolphin”, though the current trend is “dolphinfish” for clarity. > [@](#): > > there has never been even _one_ verified attack on a human by a porpoise. That alone should tell us something. > [@BrainGlutton](#): > > That is not true. At least, not WRT dolphins, don’t know about porpoises. I have no idea about porpoises, but porpoises are also smaller than most humans. I suppose one can get into semantic arguments over a slightly looser phrase, “unprovoked attack”, whereby one can argue poking ice cream sticks in the blowhole definitely is provoking, and keeping a large orca in a small pool is, perhaps, an act of provocation in itself. Documenting wild dolphins or even wild orcas attacking humans would be interesting. Attacks not starting with the humans doing something stupid like catching them in fishing nets or fishing lines, or poking them with sticks. Have there even been cases of orcas attacking swimmers or surfers like with shark attacks? I know white sharks are ambush hunters, and orcas may not use the same tactics. There has been documented sexual aggression by dolphins against humans. [/QUOTE] [QUOTE=BrainGlutton] [In response to **MIchelleRose**]Actually, AIUI, there are [porpoises](https://creelmanresearchlibrary.wordpress.com/the-endless-allure-of-non-hierarchical-organizations/) and there are also mammalian [dolphins](http://en.wikipedia.org/wiki/Dolphin), two different groups of species.

They are the “wolves of the sea” and anyone with half a brain will put lots of distance between themselves and two and a half tons of sentient carnivore. So much misconception. 1. Orcas are dolphins - they are in the [Delphinidae](http://en.wikipedia.org/wiki/Oceanic_dolphin) family. That is the family with all the dolphin genuses. 2. All dolphins are carnivores. They are avid hunters. (Fact is, most sea life are hunters, barring molluscs and microscopic animals (rotifers).) 3. Reviewing wikipedia on [killer whale attacks on humans](http://en.wikipedia.org/wiki/Killer_whale_attacks_on_humans), there are only seven cases listed of wild orcas attacking humans. Only one of those attacks was fatal - in 1894 a midshipman was taken from an ice floe by an orca. Possibly mistaken for a seal. Several of the attacks appear to be mistaken identity, and aborted as soon as the orca realized the prey was not a seal. Included in this is the one surfer bitten in 1972, and a 12 year old boy who was bumped but not bitten in 2005. Also, a group of orcas tried to tip an ice floe with an explorer and his sled dog team. Possibly confusing the dogs for seals. One case the pod of orcas sank a wooden boat, but did not kill any of the people. Another case a pod of orcas attempted a “wave wash” on an inflatable zodiac boat of a crew filming them. They had been doing the wave wash on ice floes to hunt seals. A final case was a fisherman who had a bag of crayfish and urchins tied to his arm. The orca took the bag and dragged the man along with it until the rope came free from his arm. Apparently the orca wanted the stuff in the bag, not the man - he was just a victim of being tied to dinner. Attacks on humans by captive killer whales is longer, but more confusing. There does not appear to be any predation - no humans getting eaten, but some killed by being drug under water and bitten. Some could be roughhousing getting out of hand, many appear to be cases of moody killer whales acting out, or hormonal teenagers. All in all, I would say that orcas are generally fairly friendly towards humans, and the incidents otherwise all appear to be unintentional or provoked. 1. “Wolves of the sea” is rather silly - why not “lions of the sea” or “weasels of the sea”? A better case could be “bats of the sea” - they are predators who use echolocation to swoop in on unsuspecting prey. 2. Personally, I _would_ be leery of them if I ran across them in the wild, simply because of their size and the fact that they are wild animals. But I would feel much safer swimming and having an orca show up than, say, hiking in Alaska and a pack of wolves showing up, or camping in bear country and seeing a bear or two check out my campsite. > [@](#): > > Definitions: dolphins are fish, _coryphaenidae_, like the pompano.

I know a couple and they always frown when I use the term “dolphin” to describe _tursiops truncatus_. Bad form, doncha know. I don’t know who your marine biologists are, but they don’t appear to be very good ones. Dolphins are of the family Delphinidae. There are numerous genuses of dolphin, including Delphinus, Lissodelphis, Sousa, Tursiops, and several others. Also included in that family are Orcinus (killer whales), Peponosephala (melon-headed whale), Feresa (false killer whale), Globicephala (pilot whales), and Lissodelphis (right whales). All of these are considered genuses of [oceanic dolphin](http://en.wikipedia.org/wiki/Oceanic_dolphin). [Porpoises](http://en.wikipedia.org/wiki/Porpoise) share the superfamily of Delphinoidea, family of Phocoenidae. All the dolphins are Delphinoidea, family Delphinidae. The fish with the name “dolphin” is the order [Coriphaenidae](http://en.wikipedia.org/wiki/Coryphaena), species Coriphaena. They are called “dolphin_fish_” to distinguish them from the mammals, and the are now more often called “mahi mahi” to avoid confusion. [Pampano](http://en.wikipedia.org/wiki/Pompano) are of a different order, Carangidae. They are not dolphinfish.

On a similar nitpick, my daughter is completely shark-obsessed, so we read lots of books about sharks. Over and over they refer to the whale shark as the largest predator on earth.

Seems like a slam-dunk, then. That’s the way the terms are defined. How do you dispute it? Nineteen is a prime number. The Ford Focus is an automobile. Hamlet is a play, and is also sometimes a book. Of course, it is rather amusing to read Moby Dick, especially the lengthy sequences where Melville valiantly struggles to prove that whales are “fish.” Sometimes, not everyone gets the memo. (My b.i.l. is an amateur botanist, and is amused by revisions that come along in taxonomies, where a plant used to be in one family, got moved to another, then got moved back again. So, of course, it’s conceivable, although highly unlikely, that some group will decide to move the Orcas out of the Delphinidae.) (And Pluto is still a planet, dadgum it!) ---

Over and over they refer to the whale shark as the largest predator on earth. And I’m like, what about the blue whale? Just because it eats teeny weeny krill doesn’t mean it’s not devouring the flesh of the living in order to fill its belly. Well, Plankton can also be _Protista_ , _Algae_ and Archaea. So, I would not usually call a filter feeder a predator. Altho, since filter feeders do kill the plankton, under some definitions they would be included. The whale shark is by no means the largest predator on Earth, that’s the Sperm Whale. Even if you called a filter feeder a predator, several whales are bigger as you said.If filter feeders are predators, of course it would be the Blue Whale as you said. For a certain value of “fish” the whale shark is the largest “fish”. (“Fish\*” no longer has much of a useful scientific meaning- since many use it to contain both the _Chondrichthyes_ and the\* Osteichthyes\* which are not very closely related) - wiki:_A fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related groups. … Because the term “fish” is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic, and is not considered a proper grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification._ ---

I don’t know about “wolves of the sea”, but I know that orcas are “apex predators”, meaning they’re at the top of the food chain. They have no natural predators themselves. They’ll even eat great whites. So you could say they’re the “badasses of the sea.” ---

Yes, Orcas are dolphins, in that they are in the family Delphinoidea. Some people would also describe them as whales: the term is used either to describe all of Cetacea (in which case they are), or Cetacea except for dolphins and porpoises, in which case they’re obviously not whales. I was never a fan of the whale-dolphin-porpoise classification anyways. A bottlenose dolphin is much more similar to a sperm whale than the sperm whale is to a blue whale. It’s just as fun as the whole turtle/tortoise/terrapin thing. Does the term “turtle” describe all of Chelonii, or does it exclude the terrestrial species? And what the hell is a terrapin? You’ll get people arguing vehemently over what at the end of the day comes down to semantics. ---

They eat krill, which are animals, but do they also eat the plankton, too, or is that just the feedstock for the krill? Enquiring\* minds want to know. Some filter feeders sorta “hunt” krill, but others simply strain plankton. Some filter feeders have a filter which would normally allow the microscopic sized plankton to go thru, saving the “larger’ krill as their meal. (there are actually a few species of krill that get almost 6” in length, so Krill arent always so very tiny. Most are about 1cm or 1/2 inch, however. ) Krill do swarm, so a krill feeder can be sure of getting a lot of krill per “mouthful”. ---

Until this thread, I might have agreed. There is such a thing as “folk taxonomy,” and it tends to vary from academic taxonomy. There are people who think Pandas are “Bears.” Shrug. Folk taxonomy is a little like intuitive physics: it’s wrong, but worth studying, to understand why it is so compelling. (Who among us has not thought that the path of an object thrown from a spinning carousel is curved? It feels like it.) ---

(I just did a quick search, and found the adviso, “Scientists no longer believe that giant pandas are more like raccoons than bears.” I hadn’t been paying attention, and missed that memo!)
