The Antarctic shelf is inhabited by 9 philomedid species: P. c h a rc o t i, P. orbicularis  , P. assimilis  , S. gallardoi  (all from 10–15 m and deeper), P. rotunda  , A. dithrix  , S. appelloefi  (all from 60–70 m), S. tuberculata  sp. nov. and P. heptathrix  (both from 200–250 m) ( Fig. 41View FIGURE 41). The lower depth limit for P. charcoti  and A. dithrix  is 100–150 m and 200–250 m for P. rotunda  and S. appelloefi  . The lower part of the shelf is inhabited by P. orbicularis  , P. assimilis  , P. heptathrix  , S. gallerdoi  and S. tuberculata  . In the bathyal zone are found P. assimilis  , P. tetrathrix  , S. gallardoi  and S. tuberculata  , while the only philomedid species currently known from the abyssal zone are P. tetrathrix  and I. walleni  .
