Blue Whale
Balaenoptera musculus
2.25 m (range 2 m–2.5 m)
Penis length in fully grown Blue and Fin whales at South Georgia whaling stations; carcasses usually had the penis passively extruded after death (not an erection). Exact measuring landmarks not stated.
Record holder
Whalers measured blue whale penises on carcasses. In life the organ stays retracted in a groove, but after death it slides out gradually during the tow back to the whaling station.
Margin note: The whale was past caring by then.

- Mackintosh & Wheeler 1929, Plate XXXIII, fig. 1: Fin whale carcass on the flensing plan at a South Georgia whaling station, with the penis extruded and standing up from the ventral surface. Shows a cylindrical tapering organ with a hooked tip. Fin whale, not blue whale: the text cites this plate for penis shape in both species.
