Anurida
Anurida is a genus of springtails (Collembola) in the family Neanuridae, established in 1865 by Laboulbène. The genus has cosmopolitan distribution with species occupying diverse habitats including intertidal marine zones, river floodplains, riparian areas, and forest ecosystems. Well-studied species include the intertidal specialist Anurida maritima, which exhibits complex tidal-entrained behaviors, and the terrestrial A. granaria, which has documented mycophagous associations. The genus shows notable morphological diversity in chaetotaxy and eye reduction, with some species groups exhibiting cryptic genetic divergence despite morphological similarity.

Cediopsylla simplex
Cediopsylla simplex is a flea species in the family Pulicidae. Its reproductive biology is tightly coupled to host hormonal cycles, with female maturation occurring specifically on pregnant rabbits and nestlings rather than on estrous does. The species has been described as "hormone bound," indicating that its breeding cycle is controlled by and synchronized with the breeding cycle of its host. This physiological dependency represents a specialized adaptation among fleas.
