Diving in the Red Sea

Under the Carribean is the name of a film that was filmed between August 1953 and April 1954 during Hans Hass's exhibition to the Galapagos on his research ship Xarifa. The expedition members' work on board and under the water, as well as their new discoveries, make up the material for this documentary, which is embedded in a fictional plot. Lotte Hass, an underwater model, is one of the main actors.

In this 1947 film by diving pioneer Hans Hass, marine biology work is shown with the help of early diving equipment. During the expedition Hass was able to observe and film shark behaviour and collect plant samles from underwater caves.
