We use multivariate statistics to quantify phenotypic differences within and among subspecies and species in aspects of pigmentation, caliper-based morphometrics, geometric morphometrics, meristics, and osteology.

Abstract The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted eurytopicand phenotypically variable fish species in South America, with a geographic range of about 14 million km 2from the Llanos of Venezuela to the Pampas of northern Argentina.
Entered by Torres, Armi G. The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted eurytopicand phenotypically variable fish species in South America, with a geographic range of about 14 million km 2from the Llanos of Venezuela to the Pampas of northern Argentina. Like other Gymnotids, it produces a weak electric field using specially-adapted muscle tissue located towards the tail.
A review found that these were insufficient for recognizing the populations as separate species, but did recommend recognizing them as subspecies: You can sponsor this gymnotud. Summary page Point data Common names Photos.

The male sits on a depression with its anal fin expanded horizontally guarding a cluster of larvae. Inhabits turbid slow moving or gmnotus waters Ref. Views Read Edit View history. Uses its long anal fin for locomotion. Old illustrations uppermost showing shape well, lower typical colors.

Dried foods are not usually accepted. These results support the use of the subspecies, but not the species, rank to recognize and name these regionally delimited taxonomic entities.
Email this article Login required. Gymnotus carapo Linnaeus This makes it the most widespread species of Gymnotus.
Shows auditory abilities, responding best to a frequency of Hz, with an upper limit above Hz Ref. Proceedings of the Biological Society of Washington.
This allows the fish to survive in polluted or hypoxic oxygen-deficient environments, and also comes in useful when waters recede at the end of the wet season if the fish becomes stranded, for gymjotus. Central and South America: Mouth brooding by males is observed in this species Ref. Banded knifefish Old illustrations uppermost showing shape well, lower typical colors Scientific classification Kingdom: Feed live and frozen foods such as bloodwormprawns, earthworms, tubifex etc.
Tends to inhabit sluggish or still waters and seems to prefer turbid environments.

The genus Gymnotus has undergone considerable taxonomic revision in recent years, with over 20 new species being described sinceincluding several that were originally considered to be G.
The strength and details of this pattern varies, both individually and depending on cafapo. Medium, minimum population doubling time 1. Small fish will be eaten, but it can be combined with other similarly-sized species in a big enough tank.
