Palaemon paludosus
A transparent freshwater shrimp that lives among submerged plants and detritus in the lake biome. It grazes algae and biofilm, processes organic material, and may become an important middle layer between microscopic life and larger predators if the population can establish.
Current record uses Palaemon paludosus / Eastern Grass Shrimp for the freshwater glass shrimp in the lake biome. Some references and older taxonomy use Palaemonetes paludosus; treat that as the same organism for miniBIOTA research unless a later ID review says otherwise.
At least four adults were confirmed in the lake biome on April 11, 2026, though visibility limited the full count. Zoea were first observed on April 19, confirming reproduction. They remained visible for three nights and appeared to grow, but were no longer visible by May 1. Juvenile recruitment remains unconfirmed.
Functions as a benthic-to-water-column nutrient link by converting algae and detritus into shrimp biomass. In miniBIOTA, larvae are also a potential prey item for small predators.
Primarily freshwater; can tolerate low brackish conditions at species level, but this miniBIOTA record is Freshwater Lake/Lakeshore only. Sensitive larval survival is the current establishment bottleneck.
Females carry eggs until they hatch into free-swimming zoea. In miniBIOTA, zoea were first documented on April 19, 2026. This confirms breeding, but the larvae have not yet been observed surviving to the juvenile stage.
Candidate cleanup-crew species and food-web middle layer in the lake biome. Its long-term role depends on whether larvae can survive to juvenile shrimp after fish removal.
Follow this species across the habitats where it currently appears in the miniBIOTA biosphere.
