Table 5 Percentage differences in size and mass between right and left bones of forelimbs from walruses (Odobenus rosmarus).

From: Feeding behaviour of free-ranging walruses with notes on apparent dextrality of flipper use

All specimens (n = 23) Average of differences in % of bone length or mass in adults. ∑ ((R-L)/L*100)/n Average of differences in % of bone length or mass in juveniles. ∑ ((R-L)/L*100)/n
