Animal Weight Higher or Lower Game

Guess the heavier adult-weight reference

One animal shows its reference weight in kilograms. Choose whether the other has a higher or lower reference. A correct Endless answer reveals both values, a comparison and the source; press Next question to carry the challenger into the next round. One mistake ends the streak. Try 60- or 120-second Blitz for a faster game.

The first collection contains 34 familiar mammals, from small burrowers to bears, big cats and elephants. Selected pairs compare related animals and different silhouettes within useful mass bands. Photographs identify the animals; they are not shown to scale and do not reveal a measured individual's weight.

One dataset, one definition of weight

Every answer comes from the same adult-body-mass field in PanTHERIA 1.0, the August 2008 dataset published by Jones and colleagues in 2009. It provides a sex-standardized species central estimate assembled from published measurements. We convert grams to kilograms and round to three significant figures for both scoring and display. We never substitute a maximum record, a male-only maximum, a newborn weight or an invented range midpoint.

This reference represents typical adult size for trivia; it is not a worldwide arithmetic average or a fixed weight for every animal. The source allows adult or age-unspecified specimens from wild, captive, provisioned or unspecified populations, excluding pregnant females. Sex, age, locality and season affect real weights. Those limitations apply to the entire collection, including the close comparisons.

Species boundaries follow the dataset's 2005 taxonomy. Red panda, nine-banded armadillo, gray wolf and European badger use historical broad groupings, marked on their cards. The wolf row has no wild-wolf-only or subspecies breakdown; this does not establish which forms contributed measurements. Eurasian moose uses the western-Eurasian Alces alces entry; Alces americanus separately covers North America and eastern Eurasia. Each reveal identifies the scientific name and original field value, with methods, data and relevant taxonomy links. The verification date is separate from the dataset's age.

A photo is an identity clue, not a scale

A long tail, thick coat, upright pose or close camera can make one animal appear larger. Think about body volume, then use each reveal to learn the reference scale. A missed close question does not mean every individual of one species weighs more than every individual of the other.

There are no equal-value pairs. When references are close, the game compares the displayed values; it does not claim that a small numerical gap establishes a universal biological ranking. Photos show representative adults, with sex and population allowed to differ from the measurements behind the source.
