Cambarus bartonii
common crayfish, Appalachian brook crayfish, Eastern Crayfish
Cambarus bartonii is a freshwater crayfish native to eastern North America, first described from North America in 1798. It inhabits fast-flowing, cool, rocky streams and shallow lakes across a broad range from Ontario and New Brunswick south to Alabama. The species exhibits notable physiological tolerance to acidic conditions and demonstrates behavioral flexibility, including documented use of terrestrial microhabitats for overwintering. Several subspecies have been proposed but their validity remains under investigation.

Cambarus bartonii bartonii
Common Crayfish
Cambarus bartonii bartonii is a subspecies of freshwater crayfish native to eastern North America. It is a secondary burrowing species found in streams and other aquatic habitats, with documented physiological tolerance to acidic conditions. The subspecies exhibits agonistic behavioral contests between males, particularly during reproductive periods when males adopt Form I morphology with enlarged claws. It has been observed using terrestrial microhabitats for overwintering.

Cambarus robustus
Big Water Crayfish, robust crayfish
Cambarus robustus, commonly known as the Big Water Crayfish or robust crayfish, is a freshwater crayfish species in the family Cambaridae. It is native to eastern North America, ranging from several U.S. states to Ontario, Canada. The species has been studied extensively as a surrogate for federally endangered crayfish species due to its close phylogenetic relationships and similar ecological requirements. Research indicates it demonstrates significant acid tolerance compared to sympatric Orconectes species, exhibits complex agonistic behaviors with distinct initiation acts predicting contest outcomes, and occupies a partitioned trophic position in multi-species crayfish communities.

Cyphomyrmex
fungus-growing ants
Cyphomyrmex is a genus of small, drab-colored fungus-growing ants in the tribe Attini, found primarily in the Neotropics. These ants cultivate fungi in the tribe Leucocoprineae as their primary food source, with most species growing fungal nodules rather than full mycelial gardens. Colonies are typically monogynous and small, rarely exceeding 500 workers. The genus is divided into two species complexes: the strigatus complex (South America only) and the rimosus complex (southern North America to South America). Cyphomyrmex represents a basal lineage among attine ants and serves as sister group to Mycetophylax.

Faxonius virilis
Northern Crayfish, Virile Crayfish
Orconectes virilis is a medium-sized freshwater crayfish native to North America, widely distributed across Canada and the northern United States. The species is notable for its well-documented behavioral ecology, including complex social hierarchies, territorial home range behavior, and sophisticated predator avoidance mechanisms. It has been extensively studied as a model organism for agonistic behavior, chemical communication, and escape response mechanics. The species is currently expanding its range westward into Alberta and shows adaptability to varying environmental conditions, though acidification poses reproductive challenges.

Hentzia palmarum
common hentz jumper, common Hentz jumping spider
Hentzia palmarum is a small jumping spider in the family Salticidae, commonly known as the common hentz jumper. Males possess conspicuously enlarged and darkened front legs that function in visual signaling during courtship and male-male agonistic interactions. The species occurs across North America and has been introduced to Bermuda, the Bahamas, and Cuba.

Orconectes rusticus
Rusty Crayfish
Orconectes rusticus, commonly known as the rusty crayfish, is a freshwater crayfish native to the Ohio River basin in the United States. The species has become a highly successful invasive organism in northern lakes and streams across North America, where it displaces native crayfish through aggressive behavioral dominance. Research has documented its capacity for learned associations involving predator cues, complex social recognition systems using chemical signals, and flexible spatial learning. The species' invasion success stems from a combination of behavioral traits including high aggression, broad habitat tolerance, and efficient resource utilization.

Platystomatidae
Signal Flies
Platystomatidae, commonly known as signal flies, is a family of acalyptrate Diptera in the superfamily Tephritoidea. The family comprises approximately 1200 species in 127 genera, with highest diversity in tropical regions, particularly the Australasian and Afrotropical realms. Adults are characterized by distinctive wing patterns and often metallic coloration. Many species exhibit elaborate sexual dimorphisms, including extreme head modifications in males used in agonistic interactions. The family is notable for convergent evolution of eyestalks with Diopsidae, though developed through different morphological pathways.

Stenopus
boxer shrimp, coral shrimp, banded coral shrimp
Stenopus is a genus of marine decapod crustaceans comprising eleven described species, commonly known as boxer or coral shrimps. Members are characterized by enlarged, asymmetrical chelipeds used in defense and intraspecific combat. Several species, particularly Stenopus hispidus, are significant in the ornamental aquarium trade and function as cleaner organisms in reef ecosystems. The genus exhibits monogamous social structures and prominent agonistic behaviors mediated by dopamine and acetylcholine neuroendocrine pathways.

Trichoton sordidum
Trichoton sordidum is a small, flightless darkling beetle (Tenebrionidae) native to the Sonoran Desert borderlands of southern Arizona and northern Mexico. The species exhibits sophisticated behavioral thermoregulation, including photonegativity and temperature-dependent activity patterns. Under resource limitation or environmental stress, individuals form adhesive aggregations or physical clumps of 2–10 beetles as a threat evasion mechanism. Dispersal follows cohesive patterns consistent with Minimum Risk Distribution models.
