* Sample sizes low compared to other studies (N>100).
Δ Ratio calculated on numbers from different studies but from same region.
○ Uterine fecundity is higher than ovarian fecundity.
Maximum number of fetuses over maximum number of ripe ova, i.e. UOmax-ratio (expressed as %). This ratio reflects the species’ maximum capacity uterine fecundity (U) based on ovarian observations (O).
