🐺Grey wolf
El lobo gris (Canis lupus), o simplemente lobo, es una especie de mamífero placentario del orden de los carnívoros. El naturalista Carlos Linneo, en la décima edición de su obra Systema naturæ, publicada en 1758, clasificó al perro doméstico como especie distinta (Canis familiaris). Sin embargo, en la actualidad predomina su consideración como miembro de la misma especie según la secuencia del ADN y otros estudios genéticos. El primer registro fósil data de hace ochocientos mil años. Los lobos son originarios de América del Norte y Eurasia, por donde antaño se distribuían y eran abundantes. Hoy en día habitan únicamente una muy limitada porción del que antes fue su territorio. Aunque todavía hay un número aceptable de lobos en la parte continental de los Estados Unidos de América y en algunas otras regiones, la especie está listada como en peligro o amenazada. Los lobos se cazan en muchas partes del mundo por la amenaza que representan para el ganado, así como por deporte.

Global range, not sex-split. Young & Goldman 1944 (North America) give 0.66-0.97 m. The Heptner row in this file is USSR-centric and runs higher; prefer this one for a species-level figure.

Bite force593 NDetails ↓Hide ↑
Canine bite modelled by the dry-skull method (Thomason 1991) from a prepared skull; static bite at the canines, gape not stated. Not a live measurement. The skull's estimated body mass was 34.7 kg. A lever model of captive-animal skulls gives 1141 N for the same species (Rozycka et al. 2024, Animals 14:1367).

Bite force for its size136Details ↓Hide ↑
Bite force normalised for body mass: the residual of canine bite force regressed on body mass, average across the sample set to 100. Above 100 means the animal bites harder than its size predicts. Do not cross-check against Wikipedia's BFQ table, which silently mixes this paper with Christiansen & Wroe 2007 and cites a popular-science book.
