Typical representative
Uniformly scaled by nose-tip-to-tail-tip representative total length; the pose is not stretched to every descriptive dimension.
Adult Sea Otter
An adult sea otter (Enhydra lutris) is shown in a strict left-facing side projection in a calm, level swimming pose. The representative comparison model is 1.37 m long and 38.6 kg, the midpoints of NOAA's published average ranges of 4–5 ft and 70–100 lb. The image is uniformly scaled from total nose-to-tail length; its pose-dependent vertical contour is not treated as a second documented axis.

Measurement basis
The side view is uniformly anchored to the representative 1.37 m total nose-to-tail length. The displayed height is a reviewed swimming-pose envelope, not an independently sourced anatomical measurement.
