On possible venomous effects of Speleonectes sp. (Remipedia)

This study investigates the phenoloxidase activity of a glandular substance that is supposedly injected in prey by Speleonectes sp. Phenoloxidase in that substance may be derived from a hemocyanin-like component produced by glands of the injecting apparatus and may cause deleterious effects on prey....

Description
Summary:This study investigates the phenoloxidase activity of a glandular substance that is supposedly injected in prey by Speleonectes sp. Phenoloxidase in that substance may be derived from a hemocyanin-like component produced by glands of the injecting apparatus and may cause deleterious effects on prey. We describe general morphology of the postulated injection apparatus of Speleonectes sp. and measurements of phenoloxidase activity of the putative injected substance. We also describe deleterious effects of a manually injected phenoloxidase (laccase) on Palaemonetes pugio Holthuis, 1949. /// En el presente estudio se midió la actividad fenoloxidativa de una substancia que al parecer es inyectada por Speleonectes sp. a sus presas. La presencia de fenoloxidasa en esta substancia podría derivarse de un componente similar a la hemocianina, el cual se produce en las glándulas del aparato inyector y que potencialmente podría tener un efecto mortal en la presa. En este trabajo se describe la morfología del propuesto aparato inyector de Speleonectes sp. así como el ensayo enzimático de la substancia que se supone es inyectada a las presas. Además se describen los efectos de la fenoloxidasa (lacasa) en Palaemonetes pugio Holthuis, 1949.
