I think this is as deep as the title; i went on an ocean tour in biology class at STJC in CA (where my grandmother taught and was called the queen of biofeedback, unprompted, in one of my classes). That was also the class where the instructor talked about how they were looking into species such as sea lions who gain and lose weight and dont have the same cancer issues as humans.
