For example, Goss (2016) stated that at high temperatures, Daphnia suffers from a breakdown of its enzymes eventually causing it metabolic process to die and as such, it dies. This conclusion by Goss (2016) would explain why four Daphnia died during this experiment when exposed to high temperatures whereas none of them died when exposed to low and moderate temperatures. Another study highlighted in the literature review found that ectothermic animals are sluggish at night, but active during the daytime. Scientists attribute this phenomenon to low temperatures at night. This study also showed that Daphnia are less active when exposed to low temperature than they are when exposed to high
