Question: What is the most exciting thing you have discovered while diving?

Mark Hamilton answered on 11 Mar 2021:

Well, I haven’t discovered anything new to science – But, every time I have dived in a new area I have discovered lots for myself. Like how fish move, how fast they are, the sizes of corals, slight differences in colour in the same species, etc. Basically just how much variety there is and how everything interacts. But when I get to dive again after COVID, I’ll hopefully make a proper scientific discovery!
