Amphidromy is a diadromous life history pattern, common in tropical and subtropical freshwater caridean shrimps, in which adults live, breed and spawn small-sized embryos in freshwater but have extended larval development (ELD) in marine waters.
Most completely freshwater species spawn large embryos with either direct or abbreviated larval development (ALD).
An important benefit of amphidromy is dispersal among river systems via marine larvae, which increases their access to alternative habitats.
Thus, amphidromous species have much broader geographic distributions than closely related completely freshwater ones with ALD.
ALD and freshwater ELD species appear to have evolved from amphidromous species with marine ancestors.
Delivery of larvae to the sea in many amphidromous species is accomplished by upstream hatching and river drift of ...
