Cuttlefish facts:

  • Being highly sought after delicious morsels, cuttlefish are masters of camouflage, despite the fact that they are color blind
  • Cuttlefish ink was the original sepia ink used by artists
  • Cuttlefish are very intelligent - they learn and have a frustration response
  • Their blood is greenish-blue because they use a copper-containing protein heocyanin, to carry oxygen, instead of the red iron-containing protein hemoglobin
