Its body is composed of a tightly packed interior and a smooth exterior, lined by coxal plates.

[3] Crangonyx floridanus displays two sexes, male and female, and the young are hatched into a brood pouch before they are released into the water.

Some precise sites where C. floridanus can be found are at headstreams, spring-fed rivers or lakes, and areas with a high quantity of submerged vegetation.

[5] Their primary food sources are algae, aquatic plants and invertebrates, depending on their availability.

[8] Its varying characteristics and high vicinity of adaptability make C. floridanus an exceptional invasive species in various ecosystems.

Crangonyx floridanus originates from the Southeastern states of the U.S., with its main concentrations in the Florida peninsula, South Carolina and Louisiana (Bousfield, 1958; Holsinger, 1972; U.S. National Museum of Natural History, 2015).

Further investigation has taken place since to confirm its identity, as it has previously been confused with other species (Crangonyx pseudogracilis) as they have vast similarities.
