This is what happens when you touch a live squid’s skin.

Video shows how the skin of the pale fish darkens instantly on being touched.

A close-up also reveals how the animal’s skin is covered in tingling black dots.

The mechanism that causes this interesting change is common in other animals such as cuttlefish and octopuses.

Cells containing a pigment in the skin of the animals can either expand or shrink, appearing to change the colour of its skin.

This makes these fish – known as cephalopods – effective hunters.

The video was captured at a restaurant in Kanazawa, Japan, on March 8.

It's strange when you see this, we think the squid are white or pink. When we touch the squid, they have a lot of colors. The colors that emerge in the places where our hands touch. It's like a leds light.
