“Is there an annotation for this [swim bladder of a fish]?”
I guess the annotation is, “Dead, Organism”.
If you search the top threads of all time, ranked by number of replies, “Let’s Talk Annotations” is #6.

My personal understanding is that annotations serve two main purposes, and probably lots of lesser purposes, but the two main purposes are:
- To help with phenology
- To improve search filtering
Annotations cannot be all things to all people. You have to balance usefulness with complexity. More complexity reduces usefulness for most users. Look at observation fields, which are a chaotic mess.
What would be the use case for an annotation of “Body Part”?
It would make for interesting predation studies. E.g., wings of birds are often found alone, without the body. And different predators have different ways of dismembering their prey. But we already have “Dead, Organism” for that, IF the observation is annotated, which many are not.
