Why so blue? The hummingbird bobtail squid (Euprymna berryi) gets its striking color from pigment-holding cells called chromatophores distributed throughout its body. Native to Indo-Pacific waters, it lives on the ocean floor where it burrows beneath sand to rest or hide when under threat. It’s a tiny squid: males only reach sizes of around 1.2 inches (3 centimeters), while females grow up to 2 inches (5 centimeters).
