The razorfish (Aeoliscus strigatus), also known as the shrimpfish, is a slender, tropical reef species famous for its vertical swimming posture. Found throughout Indo-Pacific coral reefs, it hovers head-down, gliding in tight, synchronized groups that mimic sea grass, coral, or even long-spined sea urchins for protection. With a body shaped like a razor blade and encased in armor-like transparent scales, this species is an expert at camouflage and stealth.
