Shorterbodied

Shorterbodied is a descriptive adjective used in biology to indicate that an organism or a group of organisms has a relatively shorter body length or trunk, in comparison with related taxa or a defined standard. The term appears in taxonomic descriptions, morphometric studies, and field guides. Spelling varies by style; hyphenated forms such as "shorter-bodied" are common, while some sources may render it as a single word depending on journal conventions.

Characterization relies on morphometric data. Researchers typically report ratios or measurements such as total body length, trunk length, or snout-vent length, and compare them to related forms or population means. The designation is inherently comparative: a form is described as shorter-bodied in relation to a closely related taxon or an established reference.

Uses include taxonomic diagnosis, descriptions of evolutionary or developmental trends, and studies of body-plan diversity. It is often discussed alongside longer-bodied or elongate phenotypes. Shorter-bodied morphology can reflect various ecological or life-history factors, but the term itself does not specify cause.

Because body proportions vary with growth, environment, and measurement method, authors typically specify the basis of comparison and the sample used to define "shorter" in that work. The term does not constitute a formal taxonomic rank and should be interpreted as a descriptive, context-dependent characteristic.
