Clistoronia magnifica
northern caddisfly
Clistoronia magnifica is a species of caddisfly in the family Limnephilidae, commonly referred to as a northern caddisfly. It is known from North America and has been the subject of laboratory toxicity studies examining the effects of heavy metals on its aquatic life cycle. The species completes a full life cycle from egg through larval, pupal, and adult stages in freshwater environments.
Palaemon pugio
daggerblade grass shrimp
Palaemon pugio, commonly known as the daggerblade grass shrimp, is a small, transparent caridean shrimp native to estuarine and tidal marsh habitats of the western Atlantic Ocean and Gulf of Mexico. Adults reach approximately 5 cm in length and exhibit yellow coloration with brownish spots. This species serves as an important ecological component in salt marsh food webs, accounting for a substantial portion of nekton biomass and functioning as prey for commercially important fish species. The species has become a standard test organism in toxicological research due to its sensitivity to environmental pollutants.
