  • 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.

  • Porcellionidae

    Porcellionid Woodlice

    Porcellionidae is a family of terrestrial isopods (woodlice) containing approximately 530 species across 19 genera, distributed on every continent except Antarctica. Members are distinguished by flattened, spear-shaped uropods that extend beyond the terminal exoskeletal plate and slightly flared epimera on the thoracic exoskeleton. Unlike members of Armadillidiidae, porcellionids cannot roll into a defensive ball.

  • Stenopus hispidus

    banded coral shrimp, banded cleaner shrimp, coral banded shrimp

    Stenopus hispidus is a marine decapod crustacean in the family Stenopodidae, recognized as one of the most widely distributed cleaner shrimps in tropical seas. The species reaches 60 mm in total length and exhibits striking red-and-white banded coloration on the carapace, abdomen, and enlarged third pereiopods. It is exclusively monogamous, with pairs occupying reef territories 1–2 meters in diameter. The species advertises cleaning services to client fish through a distinctive "dancing" behavior involving lateral antennae movement, and removes parasites, fungi, and damaged tissue using its three pairs of claws. Females are typically larger than males and carry externally fertilized eggs until hatching.

  • Telenominae

    Telenominae is a subfamily of parasitoid wasps in the family Scelionidae (formerly placed in Platygastridae). Members are solitary egg parasitoids, primarily attacking eggs of Hemiptera, particularly stink bugs (Pentatomidae) and related families in the superfamily Pentatomoidea. The subfamily includes genera such as Telenomus, Trissolcus, Phanuromyia, and Eumicrosoma. Several species, notably Trissolcus japonicus (the Samurai Wasp), are used or studied as biological control agents for agricultural pests.
