Therapy practice icon

We are looking for someone to design an icon for our new therapy practice. We love the icon used by the Monterey Bay Aquarium (I've attached a photo). Of course, we can't use the exact icon but would love to get close to that. Whatever elements need to be changed would still reflect the ocean and be simplistic and minimal. We particularly want to include the kelp and kelp bulbs as that is a part of the local environs of our area. Perhaps you could include profiles of sea mammals. Our practice is near the ocean and we love what the elements of the ocean represent. (Please do not include shells as someone else tried to do that; it looked like a drawing in a gift shop.) Our practice is named: South Bay Center for Sexual Health

We like the font used in the Monterey Bay Aquarium, however, we prefer that our icon be larger than they represent theirs to be.
