Thus, the definition of herpetology can be more precisely stated as the study of

fish, but it is not uncommon for herpetological and

scientific societies to collaborate. Examples include publishing joint
journals and holding
conferences in order to foster the exchange of ideas between the fields, as the
American Society of Ichthyologists and Herpetologists does. Many
herpetological societies have been formed to promote interest in reptiles and amphibians, both
captive and wild.

Naming and Etymology
The word ''herpetology'' is from
Greek: ἑρπετόν, ''herpetón'', "creeping animal" and , ''
-logia
''-logy'' is a suffix in the English language, used with words originally adapted from Ancient Greek ending in ('). The earliest English examples were anglicizations of the French '' -logie'', which was in turn inherited from the Latin '' -logi ...
'', "knowledge". People with an avid interest in herpetology and who keep different reptiles or amphibians often refer to themselves as "herpers".
"Herp" is a vernacular term for non-avian

s. It is derived from the old term "herpetile", with roots back to
Linnaeus's classification of animals, in which he grouped reptiles and amphibians together in the same class. There are over 6700
species of amphibians
and over 9000 species of reptiles.
In spite of its modern taxonomic irrelevance, the term has persisted, particularly in the names of herpetology, the scientific study of non-avian reptiles and amphibians, and
herpetoculture, the captive care and breeding of reptiles and amphibians.
Subfields
The field of herpetology can be divided into areas dealing with particular

Taxonomy is the practice and science of categorization or classification.

groups such as frogs (
batrachology),
snakes (ophiology or ophidiology), lizards (saurology) or
turtles (cheloniology, chelonology or testudinology).
More generally, herpetologists work on functional problems in

Careers
Career options in the field of herpetology include, but are not limited to
lab research,
field studies and survey, zoological staff, museum staff and college teaching.
In modern academic science, it is rare for individuals to consider themselves a herpetologist first and foremost. Most individuals focus on a particular field such as
ecology,
evolution,
taxonomy,
physiology, or
molecular biology, and within that field ask questions pertaining to or best answered by examining reptiles and amphibians. For example, an
evolutionary biologist who is also a herpetologist may choose to work on an issue such as the evolution of warning coloration in
coral snakes.
Modern herpetological writers include
Mark O'Shea and
Philip Purser. Modern herpetological showmen include
Jeff Corwin,
Steve Irwin, popularly known as the "Crocodile Hunter", and the star

Study
Most colleges or universities do not offer a major in herpetology at the
undergraduate or even the
graduate level. Instead, persons interested in herpetology select a major in the
biological sciences. The knowledge learned about all aspects of the
biology of animals is then applied to an individual study of herpetology.
