background: acanthocephalans are fish parasites of worldwide distribu-tion, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. no diagnostic tool is available except postmortem inves-tigations and identification by parasitologists. the aim of present study was to explore and assign taxonomical status to pallisentis species prevalent in food fishes of river g...

ammonia is the chief excretory product in fishes. however, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. in the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in channa gachua. circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...

The objective of this study was to examine how the respiratory metabolism of the snakehead Channa argus changed when it shifted from breathing water to breathing air, and how increased metabolic demands caused by temperature, feeding, and exhaustive exercise affect its survival in air. The results demonstrated that the oxygen consumption rate (MO2) of the snakehead was lower for aerial respirat...

Background Congeneric species of reptiles frequently exhibit partitioning in terms of their use of habitats or trophic resources in order to reduce competition. In this study, we investigated habitat use by two species of European skinks: Chalcides bedriagai and Chalcides striatus, based on 49 records from southern France, Spain, and Portugal. Methods We measured three levels of niche descrip...

BLAISE: blaschkolinear acquired inflammatory skin eruption INTRODUCTION Blaschkolinear acquired inflammatory skin eruption (BLAISE) encompasses a variety of skin conditions in children and adults that show striking distribution along the lines of Blaschko and are characterized histopathologically by an inflammatory infiltrate. The most common presentations of BLAISE are blaschkitis, which affec...

Snakehead fish or Channa Striata is a type of freshwater that has high economic value in Indonesia. Aims this study was to evaluating the effect adding different protein sources snakehead feed on growth, blood glucose levels, and albumin content (Channa Striata). This consisted 3 treatments each given 6 replications. Treatment A: Use made from nilem flour. B: golden snail flour C: earthworm The...

Further studies on new specimens of the rare genus Physoctonus Mello-Leitão, 1934, lead to the description of a third new species. Until now only Physoctonus debilis (C. L. Koch, 1840) and Physoctonus striatus Esposito et al., 2017, were known from sites located in the caatingas of the north-east region of Brazil. The new species of Physoctonus was collected by the French arachnologist J. Vella...
