Aeginina
skeleton shrimp
Aeginina is a genus of caprellid amphipods containing at least two described species: Aeginina longicornis and Aeginina aenigmatica. These small crustaceans are commonly known as skeleton shrimp due to their elongated, stick-like appearance. The genus was established by Norman in 1905 and occurs in marine environments of the North Atlantic.
Ramellogammarus
Stumptown scud (R. similimanus)
Ramellogammarus is a genus of freshwater amphipod crustaceans in the family Anisogammaridae, established by Bousfield in 1979. The genus includes species with highly restricted geographic distributions in the Pacific Northwest of North America. R. similimanus, known as the Stumptown scud, is endemic to the Portland metropolitan area of Oregon, while R. vancouverensis occurs in British Columbia.
Xyloryctes
rhinoceros beetles
Xyloryctes is a genus of rhinoceros beetles in the family Scarabaeidae, tribe Oryctini, subfamily Dynastinae. The genus contains approximately 13 described species distributed primarily in the Nearctic and Neotropical regions. Adults are characterized by prominent cephalic horns, particularly in males, and are nocturnally active, frequently attracted to artificial lights. The genus has been documented as a vector for the giant thorn-headed worm of swine (Macracanthorhynchus hirudinaceus), with X. satyrus representing a newly recorded host for this acanthocephalan parasite.
