An aquatic plant with a spongy stem whose long tubular outgrowths are capable of emitting a painful electric charge. Two varieties have been recorded, the first can be found on the edge of lakes, the second on the lake bed, the former being distinguished physically by its brighter colors. The stinga, like all intelligent plants, will not attack homins unless menaced, in which it uses its electric organs to send out an powerful charge that will slow down the aggressor.
