"corella eumyota" is a suspension feeder, creating a current to draw water in at one siphon, filtering out the food particles and expelling the water through the other siphon. it largely feeds on organic particles stirred up from the sediment. in its native antarctic waters, this is a slow-growing, long-lived species. it spawns in the austral summer. the larvae are retained inside the body cavity until they are well-advanced; when they are released they settle on the seabed within a few minutes, so groups of this sea squirt are found growing quite close to each other.
