An Ocean of Possibilities.

Seeking healthier options for natural healing of cancer and chronic diseases through Marine Organisms and Functional Medicine.

About Dr. Mollusk

What’s our story? was started as a tribute to Dr. Fabio Moretzsohn De Castro, Jr., who was a professor of biology in the Department of Life Sciences at Texas A&M University Corpus Christi (TAMUCC). Prior to working in the Department of Life Sciences, Dr. Moretzsohn worked at the Harte Research Institute (HRI) for Gulf of Mexico Studies, also located on the campus of TAMUCC. Dr. Moretzsohn’s passion and academic background was in biology and marine malacology (ocean mollusks). On January 8, 2019, Dr. Moretzsohn was diagnosed with Stage 4 lung cancer (non-smoker).  He passed away from cancer treatments on January 6, 2020, less than one year later.

His wife, Heather, started to raise awareness and create an online community about options to heal cancer and chronic diseases naturally through functional medicine techniques and marine organisms.  You can read more about Dr. Moretzsohn and natural healing options for cancer and chronic diseases in the book written by Heather Moretzsohn called “Ocean of Possibilities: Maximize Natural Cancer Healing with Marine Organisms and Functional Medicine,” which is available on as well as on the store of this website.  Books by Dr. Moretzsohn are also available on or on the store on this website.
