mystery Acari found in sea urchin larva culture

mystery Acari found in sea urchin larva culture
Guelpg, Ontario, Canada
August 14, 2017
We found this in our sea urchin larva culture. It is approximately the same size as the one month old larva, maybe slightly bigger. We found two identical specimens in the same culture. They were both able to survive under water for at least an hour, probably more and seemed to move around relatively freely. We removed them right away and took pictures of one under two different microscope. Will these harm the larva or eat them?
