speed in months with increased levels of benthic nutrient enrichment via marine snow. Research studies focused on the feeding and foraging habits of C. armatus has revealed that this species follows an active foraging strategy consistent with the optimal foraging theory. C. armatus has been observed to maintain low metabolic rates and slow aerobic activity in their foraging; these behaviors are thought to reflect a need to conserve energy due to the extreme environmental conditions and food scarcity that exists in C. armatus' natural habitats.
