Richard E. Young and Katharina M. Mangold
| Hooks from the proximal region of the hectocotylus
( P. margaritifera, P. addolux redrawn from Young,
1972; P. serrata redrawn from Riddell, 1985). The hooks of
the first two species exhibit their true relative differences in
size but not the third species. The hooks of P. serrata are
stated to be much larger than those of P. addolux but the
magnitude of the difference was not reported. |
