Scientific Name of Guppies

It is essential to understand the scientific name of a species to appreciate its unique characteristics. The scientific naming system, also known as binomial nomenclature, was developed by Swedish botanist Carl Linnaeus in the 18th century. The system consists of two parts โ€“ genus and species โ€“ and employs Latin or Greek words for naming.

The scientific name for guppies is Poecilia reticulata. The genus Poecilia encompasses various small freshwater fish species belonging to the family Poeciliidae, including mollies and swordtails.

The species name reticulata comes from the Latin word “reticulum“, meaning net-like or meshed. This refers to the intricate pattern on their bodies, which has made them popular in aquariums worldwide.

The Meaning Behind the Name

The specific epithet “reticulata” aptly describes the unique pattern on guppies’ bodies with iridescent spots resembling a net or mesh. In contrast, the generic name “Poecilia” has a more interesting history behind it.

In ancient Greece, poets used “poikilos”, meaning spotted or variegated, to describe poetry’s style and imagery.
Thus, when Linnaeus discovered these dazzling little fish in Trinidad and Tobago during his travels throughout Europe’s colonial era, he named them after this poetic term due to their colorful patterns.

It’s not often that you find such beauty in something so tiny yet so captivating!
