From 1972-87, I worked as a professional scuba diver for Marine World/Africa USA, an aquarium-zoo in Redwood City, California. Most of the work was plain hard labor, scrubbing algae off the walls, floors, and windows of the giant salt-water tanks. But the creatures we swam with? Sharks, dolphins, eels, seals and killer whales — magic.
Sometimes we brought the dolphins to the vets for medical attention. This was not always as easy as it might sound. In later years, tanks were made with rising floors, which made the situation less stressful for all concerned.
