The Heaviest Fish in the World: Meet the Colossal Squid and Giant Whale Shark When we think of the heaviest fish in the ocean, one species immediately comes to mind: the gentle giant of the deep, the colossal squid—but technically, the title often goes to the whale shark, the largest fish alive today. However, the true undisputed champion of sheer size and heft is a lesser-known marvel: the giant whale shark (Rhincodon typus), followed closely by the colossal squid (Mesonychoteuthis hamiltoni)—though the latter’s weight remains largely inferred due to scientific limitations. In this comprehensive guide, we explore the heaviest fish and fish-like creatures in the ocean, revealing which truly holds the crown and why these marine giants continue to fascinate scientists and dreamers alike. ---
