Metabolism of Pelagic Cephalopods as a Function of Habitat Depth: A Reanalysis Using Phylogenetically Independent Contrasts.(Statistical Data Included)
|
BRAD A. SEIBEL [1][*]
DAVID B. CARLINI [2]
Metabolic rates of deep-living animals have been intensely studied [1]. Within pelagic fishes, crustaceans, and cephalopods, a strong decline in rates of mass-specific metabolism with depth has been observed. Childress and Mickel [2] put forward the visual interactions hypothesis to explain this general pattern. Their hypothesis states that reduced metabolic rates among many deep-sea pelagic taxonomic groups result from relaxed selection for strong locomotory abilities for visual predator-prey interactions in the light-limited ...
