Callibaetis floridanus
small minnow mayfly
Callibaetis floridanus is a small minnow mayfly (Ephemeroptera: Baetidae) native to North and Central America. The species inhabits diverse aquatic environments including coastal ponds subject to saltwater intrusion and temporary wetlands (playas) in arid regions. Research demonstrates significant physiological plasticity in ion regulation, with populations capable of acclimating to salinities ranging from 113 to 9,921 µS/cm. Naiad development averages approximately 24 days from egg hatch to adulthood.

Palaemon vulgaris
Marsh Grass Shrimp, Common American Prawn, Common Grass Shrimp, Marsh Shrimp
Palaemon vulgaris is a small, transparent caridean shrimp native to the western Atlantic Ocean. Adults reach less than 5 cm in length and display distinctive orange pigmentation on the eyestalks. The species has been studied for its specialized swimming mechanics, employing metachronal beating of pleopods and drag-reducing mechanisms during locomotion. It occupies coastal and estuarine habitats from Cape Cod Bay to the Gulf of Mexico.

Pugettia
kelp crabs
Pugettia is a genus of marine kelp crabs in the family Epialtidae, distributed across the North Pacific from North America to East Asia. Species inhabit shallow subtidal zones, primarily associated with macroalgal habitats including kelp beds, Sargassum stands, and red algal turfs. Many species exhibit ontogenetic habitat shifts, with juveniles and smaller individuals occupying deeper algal turfs while larger adults migrate to shallower macroalgal beds. The genus includes approximately 25 extant species plus one fossil species, with several species serving as important subjects for studies of crab growth, reproduction, and habitat ecology.

Trichonephila clavata
Jorō spider, Joro Spider, Parachute spider
Trichonephila clavata, commonly known as the Jorō spider, is a large orb-weaving spider native to East Asia that has become established as an invasive species in the southeastern United States since approximately 2010. First confirmed in Georgia in 2014, it has expanded rapidly across multiple states through a combination of ballooning dispersal and human-mediated transport. The species is notable for its substantial size, striking coloration, and extensive golden webs, but poses minimal risk to humans due to small fangs and docile behavior. Its physiological adaptations—including higher metabolic rate, faster heart rate, and greater cold tolerance than its congener Trichonephila clavipes—suggest potential for continued northward range expansion.
