0 to 842m, but not usually found shallower than 20m. Corella eumyota occurs on a variety of substrates around Antarctica and the Sub-Antarctic and in temperate waters such as New Zealand, South Africa and southern Australia. It has also been recently (July 2002) found off northern France where it has probably newly invaded from southern waters. This is the first record of it in the northern hemisphere.
Corella eumyota has been shown to grow fast at first (up to 14.4cm in two years), but growth slows as it gets older. It is a suspension feeder, mostly on material stirred up from the substrate. It broods its young until they are well developed and they settle a few minutes after release, so Corella eumyota is often found in clumps. Spawning occurs in the Antarctic summer.
