Ameletus velox
Ameletus velox is a North American mayfly species described by Dodds in 1923. It belongs to the family Ameletidae, a group of predatory mayflies known for their distinctive larval morphology and behavior. The species is part of the Nearctic fauna with documented presence in North America. As with other Ameletus species, it likely inhabits cool freshwater streams, though specific ecological details for this species remain limited in available literature.
Pandalidae
pandalid shrimp
Pandalidae is a family of caridean shrimp commonly known as pandalid shrimp, characterized by two distinctive morphological features: a subdivided carpus on the second pereiopod and the absence of chelae (claws) on the first pereiopod. Members of this family are predominantly cold-water species, with tropical representation occurring primarily through deep-sea forms. The family holds significant commercial value, as many species are edible and support important fisheries. The genus Physetocaris, formerly included in Pandalidae, has been reclassified into its own family Physetocarididae.
Protanypus
Protanypus is a genus of non-biting midges in the subfamily Diamesinae of the family Chironomidae. The genus comprises approximately 10 described species distributed across Europe, North America, and Asia. Species within this genus are found in aquatic environments, with larvae inhabiting freshwater habitats. The genus was established by Kieffer in 1906.
