Abstract: Fish-hunting cone snails utilize rapid physiological and biomechanical mechanisms to subdue their prey. In the Schulz lab we take an integrative approach to the study of prey capture that spans molecular to field studies. The fish-hunting cone snail, Conus catus, injects a potent cocktail of peptide neurotoxins through its radular tooth into fish prey that rapidly disrupts coordinated swimming activity resulting in spastic paralysis. The venom peptides that induce this spastic paralysis are members of a novel family of highly post-translationally modified neuroexcitatory peptides. Our lab is currently investigating the evolution, physiology and molecular target of these neuroexcitatory peptides.
