"Rockhopper is the brilliant invention of Justin Blake, who has entranced a multitude of tourists with his joyous knowledge about the riches of our coastline, and whose ‘Just On Marine’ newsletter is a fount of information."
— PROF GEORGE BRANCH, Marine biologist & author: Living Shores and Two Oceans
"Justin is super knowledgeable and took all of our detailed - and sometimes challenging - shark questions in stride. This was one of the most enjoyable things I've done in the past couple of months."

"I have still not recovered from the high I got from our Airbnb experience… Sharks. I thought they were cool before this, and now… oh my word. I knew nothing. They’re the coolest. I feel I should apologize to my fellow attendees for the child-like gaze of wonderment I had throughout but at the same time, sorry not sorry"
