simplifications: given their low metabolic rate and the low density of prey at such depths , vampire squid must use innovative predator avoidance tactics in order to conserve energy . given their low metabolic rate and the low density of prey at such depths , vampire squid must use predator avoidance tactics in order to save energy . vampire squid must use innovative predator on order to conserve energy due to the low metabolic rate and the low density . given their low metabolic rate and low density of prey at such depths , vampire squid must use innovative predator avoidance tactics in order to conserve energy . 1 . given their low metabolic rate and the low density of prey at such depths , vampire squid must use new and cutting edge predator avoidance strategies in order to save energy . as the metabolic rate and density is low of vampire squid which are found in depth of oceans , they must use innovative predator avoidance tactics to conserve energy . given their low metabolic rate and the low density of prey at such depths , vampire squid must use innovative predator avoidance tactics in order to conserve energy . given their low metabolic rate and the low density of prey at such depths , vampire squids must use modern predator avoidance tactics to conserve energy .
