An adult cow fled into a dense stand of Hydrilla and rested on the bottom under cover. A cow with calf that I had pressed for 10 minutes sought seclusion in the heart of a bed of Myriophyllum. While in hiding, manatees seemed to breathe with unusual stealth, but there was no indication that they remained submerged for abnormal lengths of time. ^- On a few occasions, I managed to follow manatees closely in the runabout without disturbing them. The animals seemed unaware of the boat and the sound of its motor. One cow even collided with the bow on surfacing. Perhaps the noise of a motor at close range interferes with or disrupts sound exchange between animals or in some way disorients them. Response to divers.—The manatees at Crystal River exhibited wide variation in their response to divers. Most were wary and would not permit close approach. A few of the older animals, evidently accustomed to divers, paid them little heed. Manatees that were unfamiliar with divers tended to investigate them with cautious cu- riosity, then fled. Timid animals were often torn between flight.
