Characteristics of the Steno Rostrated Dolphin
The Steno rostrated dolphin (Steno bredanensis), a distinctive member of the Delphinidae family, is particularly notable for its unique morphology and adaptive abilities. This marine mammal, measuring between 2 and 2.5 meters in length, is distinguished by a robust body and a narrow, elongated rostrum, a feature that gives it its name. Its color varies from dark gray to slate blue on the back, with lighter flanks and a white belly, providing natural camouflage in the water. A distinctive feature of this species is the absence of a prominent frontal bulb above the beak, a common characteristic in other dolphins.
These cetaceans have powerful pectoral fins and a falciform dorsal fin, giving them remarkable agility in the water. Regarding their longevity, Steno rostrated dolphins can live up to 30-40 years, a quite advanced age for a dolphin. Their hearing acuity and echolocation skills are extremely developed, allowing them to navigate and hunt efficiently in various aquatic environments.
These dolphins are also known for their social behavior, living in groups called “pods” , where they communicate using complex whistles and clicks. Adapted to a wide range of marine habitats, Steno rostrated dolphins demonstrate great adaptability, making them capable of surviving and thriving in different environments, from shallow coastal waters to open and deep oceanic zones. Their resilience and behavioral flexibility make them a key species in the study of marine biodiversity.
