    Totally amazing. I'm overwhelmed. Where can we see more?

    Do you do this as a hobby, or do you make money from this?

    Fantastic photo's once again. With regards to the Diadema urchin spine, I always thought the barbs were the other way around so as to embed themselves in the flesh and be very difficult to remove without causing more damage, much like a fish hook?

    Thanks for the kind comments. I'll post more as I get time to take more photos on this site, promise.

    Just a hobby. Do not want to spoil it by commercialising it.

    Yeah that makes intuitive sense, but I think it sticks better in its prey this way round. Think of an arrow - it is sharper at the end that is pointing towards you. Idea is to penetrate, not "not being able to withdraw". At least that is my understanding - I could be horribly wrong.

    Yeah, but the barbs look as if their sharp end is pointing towards the spine tip, making penetration difficult and withdrawal easier? This makes sense to me, because the spines are there to protect the urchin, not as a hunting mechanism. The spines being brittle and breaking easily is what causes them to stay stuch in the careless reefer.
