About the author
I’m Justin Blake — marine biologist, shark scientist, and founder of RockHopper Fund NGO in Cape Town.
I translate ocean science into stories, experiences, and practical ways to help. Just On Marine brings together what I learn in the field — the wildlife, the science, and the hope behind it all.
“Clear, grounded and inspiring. I finish each issue with one small thing to do for the ocean.”
