Sphoeroides nitidus is a marine fish from the pufferfish family. It lives in coastal waters and can quickly inflate its body with water to become larger and scare away predators.
Sphoeroides nitidus differs from related puffers by small spines on the skin and features of coloration. It is important for marine nature because it controls the population of invertebrates and serves as a source of toxins studied by scientists.
Near-shore terrestrial and marine zones influenced by the sea.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
