They are typically found in shallow waters worldwide and play an important role in the marine food chain as prey for larger predators. There are several synonyms for this genus, including Caprellina, Caprellida, Caprellidea, and Caprellipus. These names may be used interchangeably in scientific literature and can refer to different species within the genus. Some common species of Genus Caprella include Caprella californica, Caprella danilevskii, and Caprella equilibra. Despite their small size, skeleton shrimps have a significant impact on their ecosystems and serve as a fascinating subject of study for marine biologists.
