“…This condition is understood to be more related to a physiological or osmoregulatory mechanism rather than being a step to reach marine environments. This rationale is the basis for advocating future experiments in this and other fields in the discussion, as recently carried out by Carvalho-Batista et al (2023), that investigated the preference of N. davidi for types of shelter and concluded that the java moss Vesicularia sp. was the most used shelter, supporting our finding of the specimens inhabiting banks of filamentous algae.…”

A shrimp specimen of the genus Neocaridina Kubo 1938, originally from Asia, was collected for the first time in a natural marine environment in Pernambuco, Brazil. This represents the first record of this genus in the South American continent. Morphological characteristics and mitochondrial and nuclear DNA sequences (COI, 16S, 18S, and H3) of the specimen were compared with other species of Neocaridina, enabling its identification as Neocaridina davidi. Finding this freshwater species native to mainland China in a marine environment was surprising. Based on prior findings in other locations, the most likely hypothesis for this unusual occurrence is that the shrimp may have been released intentionally or unintentionally into the environment by an aquarium hobbyist.
