Recreating a realistic copy of an environment isn't what I do, though it could be part of it. I rather attempt to invoke in the listener the sensation of, for example, being in an underwater palace filled with sirens.

So I do have to keep in mind the physics, accoustics, temperature, etc.. of a certain location to do that.

I don't have much knowledge of your location but I read Carribean so my first thought would be editing the sound of a steel drum as one of the main elements.

Anyway, if your question is if I can create the sound of an extinct animal whose sound was never known, no I can't, I can only create a sensation that embodies the spirit of that animal for example. If the animal's sound was known, I could recreate it yeah.
