The genus Endeavouria is similar to other closely related genera, such as Caenoplana and Kontikia, but can be differentiated by the narrower creeping sole and a thick layer of longitudinal muscle fibers beneath the ventral nerve plate.

[2] The copulatory apparatus of E. septemlineata has a big ventral fold and a small intra-antral penis papilla.

The name Endeavouria honors the flagship HMS Endeavour commanded by James Cook in his first voyage of discovery to Australia and New Zealand.

[5] Specimens of E. septemlineata show a gregarious behavior, gathering in groups of tens of individuals that remain hidden in the leaf litter and under rocks or fallen logs during the day.

[6] It has been demonstrated that in Brazil several native land planarians feed on the introduced E. septemlineata, thus possibly controlling its spread as an invasive species.
