Oriol Chias Diez (Spain) watches a common cuttlefish raising two of its tentacles while swimming among the seagrass.
Oriol had been observing the cuttlefish for more than an hour and was fascinated by its ability to change colour and shape at will. On one occasion it even disguised its arms as swaying leaves of seagrass.
Cuttlefish get their extraordinary camouflage abilities from cells called chromatophores. Each cuttlefish has around 10 million, and they turn them on and off like lights to create patterns.
They also have cells called leucophores which help by reflecting the light of their surroundings.
