I do a lot of educational writing, including textbooks, but one of my favorite assignments in this line of work is the student reader. These readers are single-subject books for kids to read independently, and because they are intended to encourage reading, they need to have topics that will appeal to kids. I just finished writing one about dangerous things on the Great Barrier Reef. I included sharks and rip currents, of course, but most of the reader was taken up with things that are venomous–and the list is pretty impressive. The stonefish is the most venomous fish in the world. The box jelly (aka sea wasp) is the most venomous jellyfish in the world. And the list goes on.
As an avid collector of seashells, I also included one of my favorite shells–the cone shell– which I’ve had the good fortune to only encounter in shell shops. The snail that occupies the most handsome of the many possible cone shells is also among the deadliest. It reminded me of why the rules for reef walking include wearing shoes and not picking anything up. If you want to see the cone snail in action, check out this National Geographic video. (And while the venomous harpoon system is amazing, the size of the snail’s mouth is also pretty stunning.)
So remember: NEVER pick one of these up if you’re on the Great Barrier Reef.
