This diorama is dedicated to a distinct species, the monk seal, the only seal that was met in the Black Sea, on the Romanian coast, in the past. The specimens appearing on our coast (from the south up to the Danube entry points) came from the colony at Cap Kaliacra, in Bulgaria.

In the ‘80 this colony disappeared further to perturbations and pollution; it seems that several specimens of monk seal could be met on the Turkish coast of the Black Sea. The species is also spread in the Mediterranean Sea and on the Atlantic coasts of North-Western Africa.

The diorama presents an aspect from the colony at Cap Kaliacra, as seen at the beginning of the 20th century, where the monk seals are remarked as well as such birds as seagulls and reptiles as the water snake.
