Vision

Cuttlefish possess both anterior and posterior binocular visual fields (Watanukiet al., 2000), which allow them to clearly see and plan their route while swimming forwards or backwards. Cuttlefish possess a single, mid-wavelength visual pigment, making them essentially color blind (Hanlon and Messenger, 1998; Marshall and Messenger, 1996; Mathger et al., 2006). Researchers observed that cuttlefish do not necessarily mimic the exact surrounding color, but shades that complement the surrounding color. This suggests that mimicry seems to be more monochromatic, meaning in tints and shades of surrounding colors.
