Abstract

A re-assessment of the diet of the Atlantic sharpnose shark Rhizoprionodon terraenovae was conducted to provide an update on their trophic level. Rhizoprionodon terraenovae primarily consume teleosts, but previously unreported loggerhead sea turtles Caretta caretta were also found in the diet. Analysis suggests that calculated trophic level may depend on diet and geographic area.

摘要

对大西洋尖吻鲛 Rhizoprionodon terraenovae 的饮食进行了重新评估，以提供其营养层次的最新信息。Rhizoprionodon terraenovae 主要以硬骨鱼为食，但以前的饮食报告中并未发现的红海龟 Caretta caretta 也在其食物中被发现。分析表明，计算出的营养层次可能取决于饮食和地理位置。
