I'm used to using plankton like a mass noun. So I would say
a single plankton as well as
many plankton.
That's not a mass noun; that's just a case where the plural and singular happen to be identical. A mass noun would be something like "water" and "milk" where the word refers to a mass, not something that can be counted (cf. a drop/drops of water/milk).
Edit: Do you guys consider a heritage language to be the same as mother tongue? I recently started taking Tamil lessons, and so am learning quite a few Tamil words. I'm not sure if those would qualify for this thread.
I once asked someone on this forum the very same question, and I think the answer I got was that you can count it as your mother tongue if you self-identify with that language. *shrug*
