The behavioural repertory for Poppiana dentata has not been previously reported in literature. Therefore, this study aimed to describe the repertory of behaviours for juvenile P. dentata, under laboratory conditions. An ethogram was used to categorize activities into seven main behavioural acts; foraging, eating, grooming, locomotion, quiescence (inactive), prolonged agonism and non-agonistic contact. Juvenile daily behaviour (n = 12) were continuously recorded over 72 hr and the time durations for each behavioural act were determined from viewing video footage (n = 864 hr). Activities over 24 hr were derived from percent daily proportions of each behavioural act. Overall, juvenile crabs spent most of their time foraging (54.8%) and resting (quiescence; 25.4%), while they performed eating (11.1%), grooming (5.3%), locomotion (2.6%) and displayed agonism (0.8%) to a lesser extent. Diurnal differences between light and dark phases were significant for foraging, quiescence and eating (P < 0.05). Time spent on grooming, locomotion and prolonged agonism were higher in the light phase versus the dark but these photoperiodic variations were not significant (P > 0.05). High occurrences of non-agonistic contact were similarly observed for light (101 events) and dark (93 events) phases, reflecting a gregarious nature for the juvenile stage of P. dentata. This behavioural repertory represents the first ethological description reported for the species.

Poppiana dentata的行为库以前没有在文献中报道过。因此，本研究旨在描述幼年P. dentata的行为库，在实验室条件下。使用行为图将活动分为七种主要行为行为；觅食、进食、梳理毛发、运动、静止（不活动）、长时间的激动和非激动接触。青少年的日常行为 (n = 12) 被连续记录超过 72 小时，每个行为的持续时间是从观看视频片段 (n = 864 小时) 中确定的。超过 24 小时的活动来自每个行为行为的每日百分比。总体而言，幼蟹大部分时间都在觅食（54.8%）和休息（静止；25.4%），而它们则在进食（11.1%）、美容（5.3%）、运动（2.6%）和表现出激动（0.8%）在较小的范围上。觅食、静止和进食的明暗期昼夜差异显着（P< 0.05)。与暗相相比，光相中用于梳理、运动和长时间激动的时间更长，但这些光周期变化不显着（P > 0.05）。在光（101 次事件）和暗（93 次事件）阶段类似地观察到非激动接触的高发生率，反映了P. dentata幼年阶段的群居性质。这种行为记录代表了该物种的第一个行为学描述。
