Abstract

the Seal Rotor, it was discovered that if, by mistake, one of the fish was not correctly released when the flap opened, so that it was hanging temptingly down from the underside of the moving box, the seals would leap out of the water and snatch it in mid-air. T i was hs so spectacular that a new version of the apparatus was constructed incorporating this feature. In the Mark I1 Seal Rotor, the box was replaced by a long arm along which three rows of fish could be placed. Each fish was clamped by its tail so that it could not fall. Now, when the release button was pressed, the flaps for one row of fish opened, but the fish did not fall into the pool. Instead they simply hung m a group from underneath the travelling arm. With this improvement, the seals not only had to chase after the box, but also had to leap repeatedly out of the water to snatch the fish. The Seal Rotor is demonstrated at a fixed time every afternoon throughout the year and has rapidly become a major ‘feeding time’ attraction for the public, in addition to providing the seals
