Oddly, binomial nomenclature permits animals to have the same genus and species name but not plants. Don’t believe me? Look at every plant name ever. The ones that approach duplication fall just short: Ziziphus zizyphus, for example. Better known as the common jujube — and shouldn’t that be its own blog post? the differentiation between the jujubes that grows in the ground and the jujubes you buy at the movie theater concession stand? — its name is spelled differently at the genus and species levels for no reason other than to avoid tautonym status. Animals and animal-namers, however, don’t have to worry about repetition, and as a result, certain species sound horribly unimaginative. Others don’t. Yes, I have listed the ones that stood out to me.
Ones that sound boring and unimaginative:
And, conversely, those who sound unusually cool for having their exotic-seeming biological name repeated twice:

ReplyDeleteThe animals, they occasionally mate in entertaining combinations.
DeleteDid you know that the boa constrictor is the only living species whose common name is also its scientific name?
ReplyDeleteI did not! That is kind of awesome. I wonder: Are there no-longer-living animals that share that honor?
DeleteYes, Tyrannosaurus rex.
DeleteTechnically you are talking about using both genus and species name in combination in common usage i.e. most people commonly say "Boa constrictor" to mean that species, not just Boa or constrictor. There are many examples of people using just a genus or species name to refer to a plant or animal e.g. capsicum or cantelope
DeleteWhat, no mention of the Linnaean classic volva volva volva?

Did not know of this! And yikes. That is quite a name. Apt, too.
DeleteMissed my favourite - Gulo gulo
ReplyDeleteI have a list of more than 800 of these tautonyms (e.g., Bison bison) and near-tautonyms (Ajaia ajaja, the roseate spoonbill). There are quite a number of these where the genus name, the species name, and the English common name are the same. Besides the bison and the gorilla, there is Lynx lynx, the lynx.. There are are several dozen plants and animals whose genus name and species name are the same in two different languages, e.g., Ursus arctos, the brown bear ("bear" in Latin, "bear" in Greek.)
ReplyDeleteHave you published this list anywhere? I'd be most interested in a copy.
DeleteHello.
DeleteLike Nicholas, I'd also like to have access to this list, if possible.
Not a scientist, just a curious animal-loving person.
Thanks!
I don't know if it's true, but it seems to be particularly common amongst birds. I was going through a book of bird water colours (Our Songbirds by Matt Sewell) and of the 53 birds listed, nine had tautonyms. You include three birds yourself, but these are different from these nine: Vanellus vanellus (Lapwing), Gallinago gallinago (Snipe), Milvus, milvus (Red Kite), Crex crex (Corncrake), Trogladytes trogladytes (Wren), Oenanthe oenanthe (Wheatear), Pyrrhula pyrrhula (Bullfinch), Carduelis carduelis (Goldfinch) and Cinclus cinclus (Dipper)
ReplyDeleteI couldn't find Gecko gecko on ITIS (integrated Taxonomic Information Service: http://www.itis.gov/), but when I broadened the search from "Exactly Like" to "containing" just gecko, it found Gekko gecko. Close enough ;-), but I thought you might like to know.
ReplyDeleteThere's a list of tautonyms on Wikipedia (https://en.wikipedia.org/wiki/List_of_tautonyms). Another one that is also its common name is Indri indri, though I must admit I've never heard of an indri before. I thought Chinchilla chinchilla sounds like a song you'd expect Dick van Dyke to sing in Mary Poppins ;-)
ReplyDeleteThere is a subspecies of Gorilla gorilla named Gorilla gorilla gorilla.
