A dolphin trainer is a professional who works with dolphins, often in aquariums or marine parks. Their primary role involves training these intelligent marine mammals to perform various behaviors and tricks for educational and entertainment purposes. Trainers use positive reinforcement techniques, such as rewards and praise, to encourage desired behaviors. In addition to training, dolphin trainers are responsible for the overall care of the animals. This includes monitoring their health, providing proper nutrition, and ensuring a safe and stimulating environment. Trainers often work closely with marine biologists and veterinarians to promote the well-being of the dolphins in their care.
