Figure 7 Pyrostephos vanhoeffeni. Drawing from the original account by Moser (1925) of a juvenile specimen (length ca. 25 mm) missing the pneumatophore and distal end (A) and a piece (length 6 mm) of another specimen including the nectosome with pneumatophore, but missing nectophores and a part of the siphosome (B), from Gauss Station, Antarctica.
