- •
Survival and development duration of Uca rapax zoea larvae varied in different salinities.
- •
Development to megalopa only occurred in salinities ≥ 25.
- •
Survival was highest and zoeal development fastest in elevated salinities (30 and 35).
- •
Early ontogenetic migration to offshore waters avoids larval mortality in Amazon estuaries.
- •
Minimum salinity requirements for successful zoeal development vary between sympatric crab species.
