In general, sensory acquisition involves two aspects: Retrieved from " https: J Comp Physiol A. Wild status The status of wild populations is unknown and hasn't been evaluated.
Its eyes are small and the fish is nocturnal as a result it prefers very dimly lit aquariums or it will become very shy. How many fish tanks do you have? Views Apteronotue Edit View history.
They can be trained to eat of your hand.
Black ghost knifefish are mildly electrogenic with lots of receptors around its head. From Wikipedia, the free encyclopedia. There are one or two reports of black ghost knifefish breeding in captivity but few details are available. Black ghost knife fish are quite shy and they dislike bright lighting.
Black ghost knifefish
Black ghost knifefish Synonyms: In captivity they will accept meaty foods such as prawns, lance fish, blood worms, earth worms and other live or frozen food.
Refers to the lack of a dorsal fin.
Such changes in frequency relevant to social interaction are called frequency modulations FMs. This page was last edited on 10 Novemberat Black ghost knifefish Scientific classification Kingdom: Black Ghost Knifefish — Apteronotus Albifrons.
BUYOLOGY DE MARTIN LINDSTROM PDF
We combine the reconstructed trajectory information with models of peripheral electric image formation and primary electrosensory afferent response dynamics to estimate the spatiotemporal patterns of transdermal potential change and apteronotue activation that occur during prey-capture behavior.
It moves mainly by undulating a long fin on its underside. Reviews in Fish Biology and Fisheries.
Their tank should be dimly lit and there should be caves for them to hide in, pieces of pipe of the right diameter are readily accepted for this. Cookies This site uses cookies: Therefore, the black albifeons knifefish uses an active and a passive electrosystem, each with its own corresponding receptor organs.
Black ghost knife fish are nocturnal. Sensory systems are faced with the task of extracting behaviorally relevant information wpteronotus complex sensory environments. A Black Ghost that is eating well is thick and growing with a rich black colored body. Fish Plants Shrimp Snails Frogs. Subdued lighting or an aquarium with overhanging or floating plants is best. In other projects Wikimedia Commons Wikispecies. Information at a glance pH: In particular, we find that the high-pass filter characteristics of P-type afferent response dynamics can serve as a predictive filter albitrons estimating the future position of the prey as the electrosensory image moves across the receptor array.
On the basis of albjfrons video recordings of black ghost knifefish Apteronotus albifrons feeding on small prey Daphnia magna in the dark, albifron reconstruct three-dimensional movement trajectories of the fish and prey. Wave-type EODs have a narrow power spectra, and can be heard as a tonal sound, where the discharge rate establishes the fundamental frequency.

Apteronotus albifrons Linnaeus The fish is all black except for two white rings on its tail, and a white blaze on its nose, which can occasionally extend into a stripe down its back. This very unique and interesting fish make a great addition to most peaceful community aquariums if its needs are met. Lower Distribution and habitat Origin: Recommended Minimum Aquarium Capacity: On the other hand, when low-frequency electric fields are generated by external sources instead of the fish itself, apteronoyus different class of electroreceptor organs is used for this passive electrolocationcalled ampullary organs.
Black Ghost Knifefish – Apteronotus Albifrons | Tropical Fish Site
The black ghost knifefish is a weakly electric fish as a result of the electromotor and electrosensory systems it possesses. By using this site, you agree to the Terms of Use and Privacy Policy. Breeding There are one or two reports of black ghost knifefish breeding in captivity but few details are available.
The black ghost knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate. Advances in the Study of Behaviour. Also in the Amazon Basin of Peru Habitat: Occurs in rapidly flowing waters of creeks with a sandy bottom Classification Kingdom:
