Widespread declines of Asian freshwater turtles demand urgent conservation action. This study used radiotelemetry to track 25 individuals of the Endangered Beale's eyed turtles (Sacalia bealei) (12 females, eight juveniles, and five males) in Hong Kong for an average of 284 days. Movement (4.7 ± 8.9 m day−1) and home range (7986 ± 9701 m2) varied significantly across reproductive class and season, with males exhibiting greater displacement distances and home ranges than females in the wet and mating seasons. S. bealei exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences. Microhabitat selection varied diurnally and seasonally, with preferences for spatial elements that likely confer concealment advantages. The species' relatively large home range and aquatic dependence highlight its sensitivity to habitat loss and poaching, stressing the urgency for immediate protection of remnant populations. Conservation efforts must prioritize critical stream habitats and leverage telemetry data for informed action.
