Diurnal rhythms of activity, sediment egestion and cryptic behaviour of Holothuria whitmaei (sea cucumber) at Ningaloo Reef, Western Australia

The diurnal rates of activity and sediment egestion on three seperate occasions in January, April and August, 2003, and the cryptic behaviour on one occasion in August, 2003 were measured to determine diurnal patterns of holothurian behaviour.

2003年1月、4月与8月的三次独立观测中，测定了海参纲动物（holothurian）的日活动速率与沉积物排出速率；另于2003年8月的一次观测中测定其隐蔽行为，以此明确海参纲动物行为的昼夜活动模式。
