Video showing the kicking action which is employed for fast sporadic movements, usually to avoid predation.
Turbinata follows a pattern known as diel vertical migration over a 24-hour period. Specifically, it has been shown to follow standard DVM, involving rising to the surface at dusk and sinking lower at dawn. This pattern is controlled by the copepods maintaining place in the water column based on the irradiance of light present, which changes most significantly around sunrise/sunset. DVM is proposed to reduce predation, by staying in lower visibility water and moving out of areas that see more active predation at different times of day.
Little is known about the life cycle of turbinata other than the basics of copepod life history. Naupilus larvae hatch from eggs which then go through several stages of development (N1-N6). Larvae change into a copepodite stage, resembling adults, with 5 different stages of development (C1-C5). Once matured (C6), these become the generally disinguished copepod adult stage which are reproductive, with the females producing eggs laid into egg sacs which are then fertilised.
