Nerve net Nerve net A nerve net consists of interconnected neurons lacking a brain or any form of cephalization. While organisms with bilateral body symmetry are normally associated with a central nervous system, organisms with radial symmetry are associated with nerve nets. Nerve nets can be found in members of the Cnidaria, Ctenophora, and Echinodermata phyla, all of which are found in marine environments. Nerve nets can provide animals with the ability to sense objects through the use of the sensory neurons within the nerve net. The nerve net is the simplest form of a nervous system found in multicellular organisms. Unlike
Phyla lanceolata 6 centimeters long and have toothed or partially toothed edges. The inflorescence, arising on a peduncle several centimeters tall, is a spherical spike of flowers which elongates into a cylindrical form as the fruits develop. The tiny, densely packed flowers are white, sometimes tinged with blue or purple. It is similar to the related species "Phyla nodiflora", but differs in having much longer and more pointed leaves. Both species are common as weeds and in the ornamental environment. Phyla lanceolata Phyla lanceolata is a species of flowering plant in the verbena family known by the common name lanceleaf fogfruit or
