The allometry of spiracles and gill slits: a window into the respiratory capacity of rays
Metabolic rate governs the pace of life through the allocation and expenditure of energy, yet metabolic rate data are unavailable for most species. External morphological traits, such as gill slits, have been used to infer respiratory physiology and metabolism in a handful of species, however, whether that pattern is generalizable across taxa is unknown. In rays, spiracle length may be adaptive…
