Michael Fineberg Photography and Scuba Instructor on Instagram: ""Sometimes, someone is obviously covered in red flags" Much like The Joker and Harley Quin, a mated pair of Harlequin shrimp (Hymenocera picta) are vividly coloured, and have a close relationship centered around love and murder. While every carnivore kills to eat, most are opportunistic hunters or proper predators, stalking and hunting their prey for a quick kill. Harlequin shrimp are the creepy couple who drag strangers (sea stars) into their lair and slowly torture them. Richelieu Rock, Thailand 3/03/2023 [Sony A7R IV, 90mm macro, AOI +12.5 diopter]"
