Choanoflagellate Colony

Caption: Triggered by the presence of bacteria, the single-celled choanoflagellate Salpingoeca rosetta divides and aggregates with its sisters into a colony. One reason may be that the colony is a more efficient way of capturing food, like a "Death Star" sitting amidst the bacteria and chowing down.
