Description

Palaemon paludosus is up to 2.5 cm (1.0 in) long and largely transparent. By manipulating the pigment granules in its body, it can produce effective camouflage against its background.[5] It is very similar to P. kadiakensis, from which it can be distinguished by the arrangement of spines on the telson.[3]

Distribution

Palaemon paludosus is common in southern states east of the Appalachian Mountains. It is also found in Louisiana, where it may not be native, and there are scattered records from further west, in Texas and California.[3] Their distribution is due to decreased susceptibility to predation because of complexity in higher habitats in Polygonum beds.[6]

Ecology

Palaemon paludosus lives in fresh water or slightly brackish water, usually in lakes.[3] It is nocturnal, remaining hidden among the vegetation by day, and emerging at night to feed on plankton.[5] It is an important prey item for a number of birds and fishes,[7] and may be considered a keystone species.[8] They reproduce sexually and will die after the spawning season is complete.[9]
