Abstract

The Whitespotted bamboo shark, Chiloscyllium plagiosum is a species of longtail carpet shark native to the Indo-Pacific region known as the Coral Triangle. Temperatures across much of the geographic range of the Whitespotted bamboo shark are rising, and it is not immediately clear if the species has the physiological capacity to withstand the impending rise in sea surface temperatures expected by the end of the century. Although listed by the International Union for Conservation of Nature as Near Threatened in 2006, their current conservation status is unknown. Indeed, thermal requirements of elasmobranch fishes in general are grossly understudied with empirical data available for only five of the more than 1200 extant elasmobranch species. The purpose of this study was to quantify thermal niche requirements of the Whitespotted bamboo shark by estimating key thermal metrics including intrinsic tolerance, upper and lower critical temperatures, thermal acclimation range, and upper and lower temperature acclimation responses. The results are interpreted and discussed in relation to current and potential future thermal conditions across the shark's traditional geographic range. The bamboo shark data presented here are the first to describe thermal requirements in a selachian elasmobranch.
