Topic: Elopomorpha


In the News (Sun 12 Oct 08)

  
  JGI HP
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.

The Atlantic taropn, Megalops atlanticus, can reach 2.5 m in length and inhabits nearshore marine tropical and substropical habitats where its "manic" leaping abilities make it a legendary sportfish.
The "true eels" (order Anguilliformes) are the largest members of the Elopomorpha (about 700 species) and possess an elongate body.
They are also characterized by a lack of a pelvic girdle and lack of pectoral fins.

My research supports collection development, preparation of material, and sharing of collection information for academic purposes.
My detailed morphological (micro and macro levels) studies of different groups of fossil and extant fishes (e.g., basal teleosts, Elopomorpha, Ostariophysi, and others) include ontogenetic development, terminal features and detection of variability of the groups.
My main goals are to understand the evolutionary transformations of different morphological systems and the phylogenetic relationships of major lineages of Teleostei.

EELS: THEIR HARVEST AND TRADE IN EUROPE AND ASIA
Eels are teleost fish (fish with bony skeletons) belonging to the superorder Elopomorpha and the family Anguillidae (Nelson, 1994).
According to the most recent taxonomic revision, the genus Anguilla includes 15 species and three subspecies (Watanabe, 2000) which can be found in all temperate and tropical waters except the southern part of the Atlantic and east coast of the Pacific (Williamson and Tabeta, 1991; Avice, 2001).
