Japanese flying squid Todarodes pacificus (Steenstrup, 1880)
The most popular cephalopod often found in Japanese supermarkets is...you guessed it, the Japanese flying squid (Todarodes pacificus)! You may be well acquainted with its flavor, but its physical structure and biology are not widely
known. Here, we present a video of the changing body color of a Japanese flying squid. The body color of a squid changes when muscle fibers surrounding small pigment-containing sacs called “chromatophores” extend and contract. Notice how the body
color changes.
