I've decided to use a porcupine pufferfish since it's more likely to be familiar with young readers, and have been researching like mad. Thanks to those of you who have offered advice already!
I'm currently working on the first round of sketches for the book, and would like to be accurate when it comes to the surroundings. Yes, I know that a Sea-Monkey is not likely to be frolicking about with a pufferfish, but this is meant to be a work of fiction.
Would anyone be able to recommend a site online where I could find accurate photos/info about the type of vegetation and marine life that would be in shallow temperate waters and tropical seas (according to http://en.wikipedia.org/wiki/Porcupinefish, that's where Bob would be living)? Or an organization/expert I could contact?
Any suggestions would be much appreciated, thanks.
Debbie
