Deep diving animals cannot use an air layer trapped in fur or feathers as insulation since gas is compressible, so that the thickness ΔR and hence the thermal resistance s =ΔR/k would decrease with depth.

However, it was noted that the heat losses through the cylindrical wall and the end caps were equal within a few percent to the heat losses of a cylinder of radius R and length L that conducts heat only through its cylindrical wall. Therefore, we approximated aquatic mammals as cylinders of length L with no thermal end losses.
