Distribution of noradrenaline-immunoreactivity in the brain of the mormyrid
teleost Gnathonemus petersii.
Moreover, on the basis of the low levels of [H.sub.2]R occurring not only in key motor telencephalic areas but also in mesencephalic and cerebella regions of the mormyrid
electric fish (Han et al.
Unlike the female mormyrid
fish, few of us like electric shocks.
Shifts in frequency tuning in androgen-treated mormyrid
[22.] Ikomi RB (1996) Studies on the growth pattern, feeding habits and reproductive characteristics of the mormyrid
Brienomyrus longionalis (Boulenger, 1901) in the Upper Warri River Nigeria.
Both of them belong to the weakly electric mormyrid
group of fishes that German and USA scientists had shown able to communicate with each other using varying pulses of high frequency electricity from organs in their tails.
The species feeds on insect larvae, especially Diptera and Trichoptera, and is the only upper Zambezi mormyrid
that feeds extensively on zooplankton.
More fish species (Mormyrid
and Hyperopsusus bebe occidentalis (Gunther), Oreochromis niloticus, and catfish) could be identified in the stomach of S.
The diet of this species in the upper Zambezi consisted primarily mormyrids
, followed by cichlids; small specimens (15cm SL) consumed more Barbus spp.
Squeakers or small catfish, and Mormyrids
- also known as elephantfish - hunt at night by emitting tiny electrical charges, but live in fear of a far larger predator.
Tilapia species were consumed with the highest frequency (18%), followed by Synodontis or catfish (14%) and mormyrops or mormyrids
