Brode, 1970, Dissert. Abstr. Internatl., Ser. B, 30: 5288–5289, suggested that Necturus alabamensis (as Necturus punctatus alabamensis), Necturus beyeri (as Necturus punctatus beyeri), and Necturus punctatus (as Necturus punctatus punctatus) form a series of intergrading populations. Species status supported by Guttman, Weigt, Moler, Ashton, Mansell, and Peavy, 1990, J. Herpetol., 24: 163–175 (who also suggested that Necturus alabamensis might be a composite of two species). The status of Necturus lodingi deserves additionally scrutiny and for that reason is recognized in this catalogue (see Necturus lodingi).  Bailey and Moler, 2003, Cat. Am. Amph. Rept., 761: 1–2, reveiwed the species. Bailey, 2005, in Lannoo (ed.), Amph. Declines: 866–867, provided a detailed account that summarized the biology and conservation literature. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 598. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 126–127, provided an account of larval morphology and biology. Chabarria, Murray, Moler, Bart, Crother, and Guyer, 2018, J. Zool. Syst. Evol. Res., 56: 352–363, discussed the phylogenetic placement of this species.
