A group of tourists on the Romanian coast witnessed an unforgettable spectacle recently. As they were enjoying the picturesque landscape and sun-drenched beaches, a wounded dolphin emerged from the sea. The dolphin, identified as the Delphinus Delphis species, had sustained multiple injuries, likely from getting tangled in fishermen’s nets.
This dramatic marine rescue mission unfolded before the tourists’ very eyes, leaving them in awe. But have you ever wondered about the marine life that inhabits the Black Sea? The sea is home to three notable species of marine mammals: the Common dolphin, the Bottlenose dolphin, and the Harbor porpoise.
Each of these species brings its unique characteristics to the waters. The Bottlenose dolphin and Harbor porpoise are more like the ‘farmers’ of the sea, sticking to coastal areas and feeding on fish or other benthic organisms. In contrast, the Common dolphin is more of a ‘jet-setter,’ preferring the offshore zones and feasting on fish suspended in the water column.
So, how can you spot a Common dolphin? Look for a bluish-gray to brown color on its dorsal side, adorned with a dashing V-shaped light lateral boundary. They also have a trendy pigmented band connecting the lower jaw to the pectoral fins, ranging from light to dark.
These dolphins are not only fashionable but also impressive in terms of size. They can grow up to 2 meters in length, with males measuring around 177 cm and females around 159 cm. Despite their delicate looks, Common dolphins are very sensitive to the harsh effects of chemical and acoustic pollution.
As social creatures, Common dolphins are often seen swimming in groups of 10-15 individuals. They are renowned for their agility, reaching swimming speeds of approximately 50 km/h. When they’re not showing off their swimming prowess, these dolphins take quick, frequent breaths, about every third second during their short-duration dives.
Common dolphins reach sexual maturity at a young age, around 2 years old, and have a relatively short gestation period of 10 months. Dolphin moms nurse their young for roughly 4 months, showcasing top-notch maternal instincts.
With a lifespan of around 25-30 years, these dolphins are gourmets of the sea, feeding on a variety of small pelagic fish, horse mackerel, cod, bluefish, and even mollusks. Their daily food intake is impressive, at around 10 kg.
Understanding and protecting these marvelous creatures is essential. The Black Sea wouldn’t be the same without the playful frolics of its dolphin inhabitants. Next time you find yourself near the Black Sea, keep your eyes peeled, your camera ready, and your heart open to the wonders of these incredible dolphins.
