Using Scientific Names

Using Scientific Names

And Adam gave names to all cattle, and to the fowl of the air, and to every beast of the field.

Genesis, 2:2, King James Bible

Common names versus scientific names

Every scientifically identified living organism (plant, animal, lichen, algae, virus, bacteria) has a scientific name and most have at least one common name.

  • Scientific names are unique names used by the scientific community to universally and accurately identify living organisms.
  • Common names are used locally and may vary widely by region or country. 

Notice that in the series on birds in this website the author starts each article with a collection of names for the bird.

Scientific nameUpupa Africana(“Upupa”: imitating the bird’s call; “Africana” –  Latin = ‘from Africa’)             

Common name (English): African Hoopoe 

Common name (Shona): mhupupu or chigubhubhu”

Common name (Afrikaans): Hoephoep

As a safari guide or hunter you will want to be comfortable with common, local vernacular and English names but also with scientific names and able to understand and use them accurately.

Where did scientific names originate from?

Linnaeus
Linnaeus

The man who formalized the modern system of naming organisms was Charles Linnaeus (1707-1778), a Swedish botanist, zoologist, and physician who.  He is known as the “Father of Modern Taxonomy” and there are still a number of species which were originally identified and classified by him.

Linnaeus’ Binomial Naming System

Linnaeus’ system is known as the Binomial Naming System, (bi = two and “nomial” = naming) referring to having or using two names and used especially to refer to the scientific names of living organisms. Each organism is referred to by its genus name followed by its species name – e.g. Felis domesticus for the domestic cat, Homo sapiens for humans, Panthera leo for lions, Crocodylus nioloticus for the crocodile.

Do scientific names have to be Latin?

When Linnaeus was working Latin was the language of science and educated people from all over the world communicated in Latin, no matter what their mother tongue. Many of the names originally given were in Latin and it is still a strong tradition to use Latin for naming new species.

In fact, however, scientific names don’t have to be Latin. A number of classical Greek words are also used but scientific names can be taken from any language. Then the rules of Latin grammar, gender and pronunciation are applied to them to make them uniform.

The names are often chosen because they are descriptive of some feature of the organism using, for example, Latin adjectives like: 

  • minuta – small
  • pica – black
  • oliva – olive
  • tenuissimus – thinnest
  • villoissimus – hairiest
  • brevicauda – short-tailed
  • longitarsus – long-legged
  • flavoviridis – golden-green

Something an organism can be named after the geographical location where it occurs:

  • caprivi
  • katombora
  • mashonus
  • tropicalis
  • namibiensis

People’s names can be turned into their Latin version. There are plants in Zimbabwe that have a species name “wildi” named after the botanist Hiram Wild (father of our contributor on plants).  When people’s names are adapted in this way apostrophies, hyphens, gaps and capitals are eliminated, e.g.

  •  obrieni – after O’Brien
  • macdonnelli – after MacDonald
  • laclairi – after La Clair

What is “Taxonomy?”

At the basis of all scientific names for living things is the science of taxonomy – which you only need to understand in a very general way. Taxonomy is the scientific categorizing and naming of life forms, putting things into defining groups on the basis of shared characteristics and then arranging the groups in bigger groupings. Each living organism ends up with a unique, “specific” scientific name or “species” name.

Taxonomy at work

The major categories of classification in this system are Species, Genus, Family, Order, Class, Phylum, Kingdom and Domain.  The smallest category is “Species”. Every living thing has its own unique species name e.g. A lion’s species name is “leo”. The species name of the crocodile in our part of the world is “niloticus”.

Who decides on the official scientific name of an organism?

Every known living organism on Earth is classified and named by a clear set of rules, hugely refined since Linneaus’ day. These days there are committees of specialized scientists (botanists naming plants, zoologists naming animals, etc.) who debate the classifications of organisms and apply the rules so that the scientific community can agree where each organism is placed in categories in relation to each other organism.

In the plant section of this website you will see an article on the name “acacia” which explains why the name cannot any longer be used for thorny African trees but is instead used for a large group of Australian trees.  This decision (which was not popular with many African botanists) was made in 2014 at the International Botanical Congress in Melbourne, Australia, after examination of huge quantities of scientific data presented by assorted expert botanists, arguing from the rules.

Taxonomy of humans

How do I show scientific names in writing?

  • The genus name is always written first, followed by the species name, e.g. Homo sapiens (i.e. human)
  • The genus name must always start with a capital letter and the species name with a small letter, e.g. Brachastygia spiciformis (i.e. msasa) 
  • If you are handwriting the scientific name should be underlined, e.g. Gloriosa superba  (i.e. flamelily)
  • If you are using a computer the scientific name should be in italics, e.g. Panthera leo.


You will also notice that when a scientist has referred to an organism by its genus and species name in an article he is she will then go on the abbreviate the genus name to its first initial for the rest of the article.

In the article on scorpions, in this website, you will find the following example.

“Common buthid species are Hottentotta and the lesser thick-tail scorpions, UroplectesHottentotta trilineatus (eastern nomad scorpion), Uroplectes flavoviridis (the yellow lesser thick-tail scorpion) and U. planimanus (orange lesser-tailed) which are found under rocks and logs while U. vittatus (striped lesser-tail) is found under the bark of trees.”

In this example the common name of each type of scorpion is used in italics after each scientific name and where you find “U.” that is an abbreviation for the Uroplectes just mentioned.

Learning Scientific Names

You will find that some of the more common scientific names will become second nature to you through repetition and others you will begin to recognise when you see them. This article provides a few pointers that will make this process of familiarisation easier.

  • Find out (look up on-line) the meaning of the Latin or Greek elements of the name – understand what characteristics are being referred to. For example, “oryx” refers to a pointy tool used by stone masons which is the shape of the antelope’s horn;
  • Make up your own associations with the sounds of the scientific names (that are nothing to do with the official meaning, e.g. maybe you have a cousin called Kobus who has some characteristic in common with a waterbuck?);
  • Learn the members of a genus together, for example, learn the different types of “Panthera” (reminding yourself that a panther is a big cat, even if they don’t occur in Zimbabwe).
  • Make yourself a set of scientific name flashcards for the most common animals, birds and plants in Zimbabwe and test yourself with them in quiet moments while you are waiting for something.
