spol reaches a dorsolaterally expansion of the spines, interpreted herein as the triangular
aliform process.
In spite of these similarities, Amphiuma vertebrae (and the fossils) differ from those of Siren and Pseudobranchus in having less extensive alar processes, lacking widely diverged
aliform processes, having postzygapophyseal crests, and in having differently positioned transverse processes.
The trochal bands are present into L6 stage larvae, when they are incorporated into the
aliform notopodia of segment B1 (Irvine et al., 1999).
odo rata is more ring-porous with more
aliform parenchyma than C.

Setiger B1 has dorsally extended
aliform notopodia, which secrete and support a mucous net.
Axial parenchyma vasicentric (in B coccinea),
