#reef squids

My first night dive at Juara Tioman area at the JSA house reef 'Aquarium' :) back in May. I definitely have a hard time IDing squids 🐙, probably a species of reef squid from genus Sepioteuthis. If you look closely, the little black pigment spots are chromatophores that aid in their camouflage. Chromatophores are skin color cells that can expand or retract to show different levels of color, reef squids and many other cephalopods can change their colors and patterns extremely rapidly.
