A profound sense of astonishment gripped onlookers as an extraordinary sight emerged from the depths of the sea along the Romanian coast. The tranquil waters revealed a wounded dolphin, its plight capturing the attention of unsuspecting tourists.
Efforts were made to rescue the distressed marine mammal, but regrettably, its fate was sealed. Experts identified the creature as a member of the Delphinus Delphis species, a species known to inhabit the Black Sea.
Upon closer examination, the dolphin displayed multiple wounds on its body, likely inflicted by the ensnaring nets of fishermen. The Black Sea is home to three distinct species of marine mammals: the Common dolphin (Delphinus delphis ponticus), the Bottlenose dolphin (Tursiops truncatus ponticus), and the Harbor porpoise (Phocoena phocoena relicta).
Diverging in morpho-anatomical features and primary food sources, these species exhibit unique characteristics. The Bottlenose dolphin and Harbor porpoise primarily feed on fish and benthic organisms, while the Common dolphin’s diet encompasses fish and other organisms found within the water column.
Each species displays a preference for specific habitats, with the first two favoring coastal areas and the Common dolphin being commonly encountered in offshore zones. The Common dolphin is characterized by a bluish-gray to brown color on its dorsal side, featuring a distinct V-shaped lateral boundary that is remarkably light. A pigmented band, varying in darkness, connects the lower jaw to the insertion of the pectoral fins. The dorsal, pectoral, and caudal fins range from black to gray-brown.
Newborns measure around 0.80-0.95 m, with adults in the Black Sea not exceeding 2 m (males – 177 cm, females – 159 cm). Highly sensitive to chemical and acoustic pollution, they exhibit social behaviors, forming groups of 10-15 individuals, as well as pairs or isolated individuals. With rapid swimming capabilities, reaching speeds of approximately 50 km/h, they engage in short-duration dives and frequent surface breathing at intervals of 1/3 seconds. Their habitat extends to depths of up to 70 meters.
Sexual maturity is reached at the age of 2 years, and the gestation period is 10 months, with weaning occurring at 4 months. Displaying highly developed maternal instincts, their lifespan is estimated to be 25-30 years. Their primary diet comprises small pelagic fish such as sprat, anchovy, and gobies, along with crustaceans.
Additionally, their stomachs often contain other species like horse mackerel, cod, bluefish, red mullet, sea bass, shrimp, and mollusks. The daily food intake for these remarkable creatures is approximately 10 kg.

Past Events
Imagine traveling back in time to the 1950s and 1960s, when rock ‘n’ roll and poodle skirts were popular. It was also a time of clever inventions, such as the old-fashioned electric knife sharpener, which revolutionized our daily cooking procedures. Before the invention of this clever device, sharpening knives required upper-body exercise and involved the use of whetstones or manual sharpeners.

2. Sharpening: Align the knife blade with the internal guides as you insert it into the slot. Pull the knife through gradually, applying consistent pressure and speed from heel to tip. The edge will be sharpened and ground by the abrasive wheels inside.
3.Repeating: Do this a few times with duller blades. For varying phases of sharpening, from coarse grinding to delicate honing, many sharpeners have numerous slots.
4. Finishing: Test the blade’s sharpness by slicing through paper or on a cutting surface after wiping off any metal shavings. And voilà! You have a brand-new knife.
