BINGO, thank you for proving my point.

Laypeople do not understand the difference between how a scientist uses a word and that muddies up the waters.

"Dolphin" does stem from that word, but when scientists use it, they are talking about mammals, not fish.

Dolphins are mammals who swim in water like fish, but they still do not have gills. They still have lungs. Swimming like a fish does not make it a fish. Whales are not fish either, but in antiquity everything that looked like a fish, gills or lungs everyone falsely thought they were fish. It wasn't until Darwin solidifying classification that distinction was made between mammals and fish. 

Remember that the next time you debate a theist arguing over Jonah an the Whale story. How many times have you heard some idiot falsely call the whale a fish? I have plenty of times in 18 years online.

You are a layperson.  

You aren't a marine biologist.

You are just being fussy because you live in your own little black or white world.

I can't imagine how you have survived having whales incorrectly categorized after all these years and the numerous occasions you have been exposed to such an atrocity.  You should sue Al Gore for inventing the Internet.

A new scientific discovery right here on the Interwebz - The Zebo Fish.  Unless you are a mammal.  Then no, you can't be a fish.

Dolphin isn't a scientific name. It's a layperson's term.

Scientific names for organisms go in this form, and the words usually in Latin:

Genus species

I fully expect that, when human civilization comes crashing down in a hail of flaming rubble, the incorrect use of the term 'dolphin' will be a contributing factor.

He's right you know.

Quote:Footage from a new BBC documentary series, "Spy in the Pod," reveals what appears to be dolphins getting high off of pufferfish. ... The dolphins were filmed gently playing with the puffer, passing it between each other for 20 to 30 minutes at a time.

How the fuck do you smoke under water?



Dolphins are not fish.

Dolphinfish (Mahi Mahi) is more like swordfish, at least in flavor. It is not a species of actual dolphin. It is not warm-blooded. Dolphins, including the killer whale, are warm-blooded.

But are they Republican?

 Not if they’re warm blooded.

ZING!

There is a two-part latin name which for each individual species and only for that species. This is commonly called a species' scientific name. It avoids MANY problems with common names:

1. A common name is often used for multiple species. This is especially true when there are similar species in different locations. There is a Red Snapper in the Caribbean and a Red Snapper in the Pacific. They are NOT the same fish. There are many examples of this confusion.

2. Often, one species will have many common names. Have you heard of a mountain lion, puma, cougar or catamount? All the same animal. There are even more regional names for this same critter. Ever heard of a Humuhumunukunukuapua? It's what the Hawaiians call what most people call the Picasso Triggerfish.

Sorry Brian but if the guy you were talking about was talking about the fish most commonly known as Mahi Mahi, he is correct. That species has just as much a claim to the common name Dolphin (mostly used on the eastern seaboard of the US) as any member of the Delphinidae family which are of course, mammals. That's the whole point of scientific names: to avoid this kind of shit. One name for each species and only for that species.

I am personally familiar with the "Dolphin" thing as I used to live in Florida and worked in the recreational scuba business as well as an Everglades tour guide. MANY Floridians angrily insist that a dolphin is a fish (Mahi Mahi) and that the animal we call a dolphin is a porpoise. The latter is incorrect. A porpoise is a similar but different family of marine mammals.

There's no winning an argument of common species names because there are often no right answers or multiple right answers.

THANK YOU!

And even if a scientist uses old language to name a "Genus/species" they are still not using that name the same way a layperson views it.

Well, many types of true bony fish (osteichthyes) are also warm blooded.  Tuna comes to mind.

Older concept that only mammals and birds are warm blooded is incorrect.   Endothermy is apparently not only a survival advantage under many circumstances, but are relatively easy to evolve.  So many other animals we would not classify as mammal and birds, including many highly active pelagic fish, have also been found to have independently evolved endothermy.

Off the Western U.S. coast these fish are called Dorado.
