REEF SQUID
Also known as the bigfin reef squid or oval squid, they have thick and muscular oval fins that extend around almost their entire mantle. They have iridophores (especially in the head) that emit iridescent metallic greens and reds when illuminated. They have leucophores – a reflectortype structural colouration that reflects ambient light, i.e., they are white in white light, green in green light. They are able to produce complex body patterns from the moment they hatch.
