Testhossza
Testhossza, commonly translated as body length, is a basic morphometric measurement used in biology to describe the size of an organism's body. It is typically defined as the distance from the tip of the snout to the posterior end of the body. However, the precise endpoints vary by taxon and purpose. In some groups, the term is equivalent to standard length (snout to base of tail) or to total length (snout to tip of tail). The term is most commonly applied to vertebrates such as fish, amphibians, reptiles, and mammals; in invertebrates the concept may be adapted to suit body plan.
Measurement is performed using rulers, measuring boards, or digital calipers. For living animals, measurements should be
Applications: Body length is a fundamental descriptor of adult size, growth trajectories, condition, and population structure.
Notes: Because definitions differ by taxon, researchers should specify how testhossza is defined in their study
