Summary The coleoid cephalopods (cuttlefish, octopus, and squid) are a group of soft-bodied marine mollusks that exhibit an array interesting biological phenomena, including dynamic camouflage, complex social behaviors, prehensile regenerating arms, large brains capable learning, memory, problem-solving [1–10]. dwarf cuttlefish, Sepia bandensis , is promising model cephalopod species due to its small size, substantial egg production, short generation time, camouflage behaviors [11]. Cuttlefish dynamically their surroundings by changing the color, pattern texture skin. Camouflage optically-driven, achieved expanding contracting hundreds thousands pigment-filled saccules (chromatophores) in skin, which controlled motor neurons emanating from brain. We generated cuttlefish brain atlas using magnetic resonance imaging (MRI), deep histology, we built interactive web tool ( cuttlebase.org ) host data. Guided observations other [12–20], identified 32 lobes, two optic lobes (75% total volume brain), chromatophore whose directly innervate chromatophores color-changing vertical lobe has been implicated learning memory. This provides valuable for exploring neural basis behavior.
