スーツ姿のサメがスキューバダイバーに握手を差し出す

An incredibly funny, high-concept book cover art titled "Manners for Sharks: How to Shake Hands Before Biting". The front cover depicts a massive, terrifying Great White Shark wearing a sophisticated tweed vest and bowtie underwater. The shark politely extends one pectoral fin to offer a gentlemanly handshake to a terrified scuba diver in mid-water. Dramatic undersea lighting, deep blue ocean rays, classic hardcover etiquette book layout, elegant typography, hilarious surreal irony, ultra-detailed textures, 8k.
