Fish and organisms from the Mediterranean are selected anddisplayed there in public view. The tanks are made of cement and their bottoms are covered with sand, shingles and corals. The water in the tanks is mainly filtered sea water.

These tanks host different kinds of sea species, such as sea
turtles, dolphins, sharps, seals, mollusks, echinoderms, crabs and many kinds of fish.
Apart from these tanks, there is also a big underground area that serves for stocking new species or sea animals that need special treatment and protection. This place is frequently used to hospitalize sea turtles and seals from the nearby waters.
The museum displays embalmed sea species, like dolphins, sea turtles and sharks that are certainly worth to visit.
The Hydrobiological Station of Rhodes runs today a lot of research on the oceanography of the Dodecanese islands and works as a model research unit in the Mediterranean area.
