Coordinated Feeding Behavior in Trichoplax, an Animal without Synapses

Coordinated Feeding Behavior in Trichoplax, an Animal without Synapses. Carolyn L. Smith et al (2015), PLoS ONE Trichoplax is a small disk-shaped marine metazoan that adheres to substrates and locomotes by ciliary gliding. Despite having only six cell types and lacking synapses Trichoplax coordinates a complex sequence of behaviors culminating in external digestion of algae. We combine live cell imaging with electron microscopy to show how this is accomplished
