How do mollusks make the complex patterns on their shells? It turns out they have part of their nervous system dedicated to sensing their shell! It can feel for defects, dissolution and even "sniff" the chemistry allowing it to change color patterns! Researchers were able to relate patterns of neuron excitation to the wavelike patterns in cone snail and clam shells! The shell pattern is made line by line by activating different pigment cells, kind of like an ink jet printer! #clamFacts
