Just checked wikipedia page... they have like 100K neurons only.. wtf!!! How can nature cramp all senses, including spatial, motion, life maintenance and general thinking into just 100K neurons?
A lot of the low level stuff is outsourced to biochemistry: the physical properties of proteins, and the various self-regulating biochemical systems of an animal, can "encode" a lot of intelligence, easing up on the computational demands of the brain proper.
