Strange AnimalsSPECIES PROFILES
One animal, everything we know
Each profile gathers the research on a single species: size, senses, evolution, behaviour and threats. Every number is graded and traced to a numbered source, and each profile ends with every article we have written on that animal.

HOW WE GRADE A NUMBER
Not every famous figure holds up
Animal facts get repeated until they sound settled. The 112 km/h cheetah is a quoted figure; the best wild measurement is 93 km/h. So every number on a profile carries one of three grades.
MeasuredRecorded directly: a timed run, a tag, a weighed animal.
EstimatedCalculated from a model or a small sample. Good, but not observed.
Quoted, unverifiedWidely repeated with no study behind it. Shown struck through.
