摘要

摘要:关于北美最大的野生淡水龟(Macrochelys属)的最大体型，已发表的文献并没有达成共识。目前已知的最大的野生苏瓦尼鳄鳄龟(苏瓦尼鳄鳄鳄龟)是一个被管理的标本，其甲壳直线中线长713毫米，最大甲壳长801毫米，最大甲壳宽619毫米，最大头宽236毫米。这只海龟从未称重，但我们使用在圣达菲和苏旺尼河研究中的形态计量学数据估计，它在捕获时重约76.4公斤(168磅)。我们95%的预测区间(67.6-86.3公斤[149-190磅])表明，推测估计和轶事报道的苏瓦尼分枝杆菌体重≥90公斤(≥200磅)是可疑的。

Maximum Body Size of the Suwannee Alligator Snapping Turtle (Macrochelys suwanniensis)

Abstract - The published literature does not provide a consensus regarding maximum body sizes of North America's largest wild freshwater turtles (genus Macrochelys). The largest known wild M. suwanniensis (Suwannee Alligator Snapping Turtle) currently exists as a curated specimen measuring 713 mm straight-midline carapace length, 801 mm maximum carapace length, 619 mm maximum carapace width, and 236 mm maximum head width. The turtle was never weighed, but we used morphometric data from our studies in the Santa Fe and Suwannee rivers to estimate that it weighed ∼76.4 kg (168 lbs) when captured. Our 95% prediction interval (67.6–86.3 kg [149–190 lbs]) suggests that speculative estimates and anecdotal reports of M. suwanniensis that weigh ≥90 kg (≥200 lbs) are dubious.

期刊介绍： The Southeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the southeastern portion of North America, roughly bounded from North Carolina south to Florida, west to Texas, north to Oklahoma, and east back to North Carolina. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
