What does this number measure?
An aquatic predator with an elongated body. Displayed dimension: representative length excluding the tail.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue value to check against the source; not individually audited.
Naturalistic illustration of a European otter; anatomy, texture and colouring are interpreted, not a photograph. The dimension of the anatomical reference is visually estimated at 83 % of the illustrated axis.
