Toxinology of Venomous Marine Worms; A Review
Although the widespread distribution of venomous marine worms around the world, the structural and toxinologcal studies of their toxins are still limited.This study was aimed to evaluate the toxicity of poisonous marine worms. Touching the cilium of Chloeia flava and Sipuncula marine worms cause painful inflammation of the skin. Many species of nemertines prey their victims by a flexible prob...
متن کاملFactors Controlling the Change of Shape of Certain Nemertean and Turbellarian Worms
INTRODUCTION Two groups of free-living, acoelomate worms, the nemerteans and turbellarians, are noted for their ability to change their shape. The role of circular and longitudinal muscles in producing these changes are well known, but since these worms are not invested by a cuticle, it is not immediately apparent what limits the changes of shape. Obviously the worms are not indefinitely extens...
متن کاملTurbellarian black spot disease in bluespine unicornfish Naso unicornis in New Caledonia, caused by the parasitic turbellarian Piscinquilinus sp.
Turbellarian black spot disease is described in a bluespine unicornfish Naso unicornis (Perciformes, Acanthuridae) collected from the wild off Nouméa, New Caledonia, South Pacific. Each cyst contained a whitish worm, 2 to 4 mm in length, which was able to swim freely in seawater. Cyst walls consisted of fibrous tissue with a scattering of melanocytes. Worms had 2 eyespots at the anterior end, a...
متن کاملThe physiological response of the marine platyhelminth Macrostomum lignano to different environmental oxygen concentrations.
The respiration rate of meiofauna is difficult to measure, and the response to variations in the environmental oxygen concentration has so far been mainly addressed through behavioral investigation. We investigated the effect of different oxygen concentrations on the physiology of the marine platyhelminth Macrostomum lignano. Respiration was measured using batches of 20 animals in a glass micro...
متن کاملReporter Dyes Demonstrate Functional Expression of Multidrug Resistance Proteins in the Marine Flatworm Macrostomum lignano: The Sponge-Derived Dye Ageladine A Is Not a Substrate of These Transporters
The marine plathyhelminth Macrostomum lignano was recently isolated from Adriatic shore sediments where it experiences a wide variety of environmental challenges, ranging from hypoxia and reoxygenation, feeding on toxic algae, to exposure to anthropogenic contaminants. As multidrug resistance transporters constitute the first line of defense against toxins and toxicants we have studied the pres...
