Torpediniformes

 

an order of fish. The body, which is flat, almost round, thick, and meaty, reaches 1.8 m in length and weighs as much as 90 kg. Electrical organs are located on the sides. Fish of the order live in tropical and subtropical seas, primarily in shallow water; some species live at depths to 1,000 m. The fish feed on bottom-dwelling invertebrates.

The order embraces three families: Torpedinidae (electric rays), Narkidae, and Temeridae. The Torpedinidae, which include seven genera with 30 species, are quite common. The genus Torpedo has an especially large number of species. The best-known species, Torpedo marmorata, was used by the ancient peoples of the Mediterranean to treat gout. Typhlonarke aysoni lives near New Zealand.

The Torpediniformes are not very important commercially.

A este respecto, Portella & de Carvalho (2013), mencionan que el desarrollo de los canales hiomandibulares alrededor de los organos electricos, representa un caracter diagnostico que agrupa a los miembros del orden Torpediniformes. Asimismo, se ha determinado que el desarrollo notable de estos canales, tambien se presenta en relacion con el tamano de las aletas pectorales, ya que entre mayor sea la superficie que cubren dichos canales, mayor sera la informacion que el organismo pueda detectar del movimiento de la columna de agua (Maruska & Tricas, 1998; Maruska, 2001; Saez et al., 2014).
Atributos que resultaron de gran utilidad para la diferenciacion de las especies bajo estudio, los cuales podran ser empleados en la clarificacion taxonomica de otros grupos de batoideos; ademas de que podrian emplearse como caracteres informativos para la reconstruccion filogenetica de Torpediniformes y batoideos en general.
