Latreutes
Latreutes is a genus of marine shrimp in the family Hippolytidae. Species within this genus exhibit distinct reproductive strategies, with documented cases of consecutive breeding and seasonal reproductive peaks. Some species, such as L. fucorum, form mutualistic associations with pelagic Sargassum algae, while others inhabit benthic marine environments. The genus shows variation in habitat preference across species, from Sargassum-associated pelagic habitats to seagrass meadows and coastal waters.

Petrolisthes armatus
Green Porcelain Crab
Petrolisthes armatus, commonly known as the green porcelain crab, is a small porcellanid crab native to the southwestern Atlantic, particularly Brazil. The species has established invasive populations along the southeastern United States coast, where densities can exceed 30,000 individuals per square meter. Genetic studies confirm it as a single monophyletic species with exceptional geographic range spanning the Atlantic and eastern Pacific. It is frequently parasitized by the bopyrid isopod Aporobopyrus curtatus, which causes parasitic castration.
