The monophyly of Elopomorpha (eels and their relatives) has long been one of the most problematic issues in systematic ichthyology.
(1966) established the Elopomorpha based on the existence of the leaf-like larval form, termed a leptocephalus, no one has corroborated their monophyly using character matrices derived from both morphological and molecular data during the last 30 years.
Mitogenomic data strongly supported the monophyly of Elopomorpha, indicating the validity of the leptocephalus as an elopomorph synapomorphy.
We hypothesize that: 1) vertebral number and aspect ratio vary independently in the precaudal and caudal regions (some elongate fishes have long bodies and others have long tails); and 2) vertebral number and aspect ratio vary independently of each other.
To test these hypotheses, we are examining vertebral column morphology in seven major clades of fishes: Beloniformes, Elopomorpha, Gadiformes, Osteoglossomorpha, Otophysi, Polypteriformes, and Scombroidei.
Preliminary results indicate that elongate members of some clades have a larger number of precaudal vertebrae but a similar number of caudal vertebrae when compared with non-elongate members of the same clade.
