Notes:
1.  The number of extant species identified is constantly changing and usually increasing in number.
2.  Weight information was often lacking in references.
3.  Weights in the Adult Ave. Wt. Used column:
a.  Where weight ranges were given in references,  the average of the weights were used.
b.  Where maximum weights only were given, 75 percent of the maximum weights were used.
c.  When only length information was available as indicated by e in the table,  rough average weights were estimated based on the lengths and weights of some other amphibians in the same group (order, or family).
d.  For three caecilians that had known lengths and widths, weight estimates were made based on these dimensions as indicated by "g' in the table.
5.  SVL and TL indicate snout-to-vent length and total length, respectfully.
