I know I'll be in the minority, but I actually do have a daughter who majored in marine biology at Oregon State and worked for several years after graduation as a dolphin trainer in Miami. After graduation she did an unpaid internship on a great white shark research program in South Africa (an expensive way to get experience but way cool), and then she did dolphin training internships in Florida before being hired permanently. She knew coming out of her major that marine biology jobs all require a year of experience before they will let you apply, and that meant doing internships (mostly unpaid). It's tough getting hired in marine biology but do-able. Following this, she realized that she was doomed to a very low salary forever as a dolphin trainer, so she decided to pursue a vet school degree and eventually work as a zoo/aquarium vet. Hopefully she will still work with marine animals but at a much higher salary.
