One identified shrimp is a record, not a population
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The species and surplus guides now include the first reported Brazilian Neocaridina davidi specimen while separating strong specimen identification from population establishment, marine tolerance and a traced aquarium release.
Why it changed
The study vouchered one 6.52 mm adult female and used morphology plus COI, 16S, 18S and H3 evidence. It did not measure ambient salinity, survival or osmoregulation, resample nearby freshwater, find a second animal, document reproduction or directly test the proposed aquarium-trade introduction route.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
