An informative journey into the magical world of seas and oceans can be made at the exhibition of deep-sea inhabitants. Captivating visitors are the mother-of-pearl shells of pearl oysters, the massive shells of Madagascar helmet shells, light and airy murex, and the Black Sea stingray with a long tail studded with dangerous poisonous hooks. Species particularly dangerous to human life are displayed separately: pufferfish, bright painted cone snails, gorgonian coral, and others. Edible mollusks such as mussels, oysters, abalone, whelks, scallops, and cockles evoke great interest.
