Archdale and Anraku (Archdale and Anraku, 2005) reported that A. aurita could capture almost all types of agar pellets, but some which contained quinine were soon rejected, which means that Aurelia can discriminate prey based on its chemical substances. These protists are referred to as mixotrophs since they can both consume organisms/organic materials and perform photosynthesis in order to get food: It's a "mix" of both autotrophic and heterotrophic ability. Each of these classifications can help shed light on how they get food and nutrition. Emerging harmful algal bloom species over the last four decades in China.
