Parr, T. Jones, G. S. Hammond, and T. A. Dewey. Although influential, the hypothesis has been difficult to test. The rate of energy intake was limited by handling time. These predatory snails consume other mollusks and are sometimes cannibalistic. Predation by naticid gastropods shows evidence of adaptation to maximize the rate of energy intake. Abstract Oxygen consumption in sea water increased with size and tissue weight of Natica maculosa Lamarck at ambient temperatures (28–29.5 dgC) and salinities (31–32‰) in a fashion comparable with other naticids.
