Warsaw, Poland — Two dolphins frolicking near the Polish Baltic Sea port of Gdynia at the weekend thrilled Polish marine biologists, who say dolphins were last seen in the area more than two centuries ago.

“Our records show dolphin sightings in this area in the 17th and 19th Centuries, so this really is a special event,” Professor Krzysztof Sikora, head of Gdansk University’s marine biology station on the Baltic’s Hel peninsula.

Sikora identified the creatures as common dolphins and urged pleasure boaters and commercial shippers to keep their eyes peeled for further sightings of the mammals.

Sightings of species have increased in recent years owing to the rise in the number of pleasure craft and the prevalence of mobile phones with cameras, Sikora said speaking via a mobile phone from a boat off the coast of the Hel peninsula.

Sikora was, however, at a loss to explain why the dolphins ventured into the Baltic.

Hazard z tą jaszczurką zielona to coś niesamowitego. Jeśli to stanowisko jest blisko Twojego zamieszkania, powłócz się tam trochę, poszperaj. Jeśli znowu znajdziesz owego gada będzie to niesamowite znalezisko, gdyż ogólnie uważa się, ze jaszczurki zielonej już u nas nie ma, tzn. nie odnotowano jej obecności od dawien dawna. A to co Tryk trzyma w rękach, to samce jaszczurki zwinki.
