WINNER, PORTFOLIO PRIZE
Male cuttlefish posture and fight to mate with females. Three large males surround what they think is a female in the foreground, but they’ve been deceived. It’s a smaller male mimicking a female to avoid confrontation and sneak up on females unnoticed. His concertinaed and patterned nearside lower arm gives his sex away.
