@s_r_constantin During my flaneuring around the aging lit, I've seen some people proposing certain kinds of fish (Like the African killfish) as models to study aging, but no one (Maybe just 1 paper) talking about daphnia. Why might this be? / Good for you, no one has realised yet

There are a couple actually. TBH it's not that Daphnia are exceptionally good model organisms for studying aging in particular, but that they're exceptionally good for in vivo pharmacology when you need a cheap way to look at chronic effects.

Choice of model organisms is extraordinarily path-dependent, from what I can gather. There are more resources for studying and working with the most-studied organisms, it's easier to get up and running quickly, so researchers have an incentive to work with "standard" organisms.

As a result, there are really only a handful of organisms routinely used in the laboratory: yeast, worms, flies, mice, rats, and sometimes rhesus monkeys. There are some eloquent voices speaking out in favor of greater diversity in model organisms, but they're a minority.
