Clams
Clams do not have a central nervous system and when compared to the ones of squids or octupi, seems like they are not even living. Clams are stationary for mmost their lifes, only moving when forced to. When laying undesturbed, the clams lay with their mouth open, catching floating particles of plankton and small oganisms. However, when a disturbance is present, the clams close quickly into a defensive position, with their hard calicum shells protecting their inner works.
Clams do have small amounts of compressed ganglia, which act as warning signals tho the colams shell. This is what desides wether to move or not, when to open or close, and when to eat.
