Octopuses excited by high definition television (HDTV)

Octopuses like to watch high-definition television (HDTV), say scientists.

In experiments evaluating how the cephalopods respond to moving images, they responded far more vigorously to HDTV than standard definition TV.

It appears their eyesight or behaviour is too sophisticated to react to lower quality images, say researchers in The Journal of Experimental Biology.

Knowing that octopuses prefer to watch HDTV gives scientists an important tool that can be used to study elements of their behaviour, such as personality.

Here a octopus reacts excitedly to a HDTV video of a crab, shown in the bottom left corner.
