Studies of the venoms of some Conidae

摘要: Abstract The venoms of fourteen species Conidae were tested on a variety animals. Venom from the posterior half venom duct Conus geographus was toxic to representatives all vertebrate classes but without effect gastropods, crab and polychaete. Injections concentrated seawater extracts resulted in flaccid paralysis skeletal musculature each tested. minimum lethal dose for mice ranged 1·.6 24·1μg (wet weight) per mouse. When injected into fish, C. catus produced symptoms similar those by venom. tulipa paralysed fish caused hyperexcitability, ataxia, dyspnea coma when mice. Respiratory failure appeared be responsible deaths with amounts , . Although not quercinus lividus some necrosis tissue haemorrhages at sites injection.
