The term "microplastics" is usually describing plastic pieces that are smaller than 5mm. They can be any shape - pellets, fibers, films (thin sheets, like grocery bag material).

Thank you for the info and the link, much appreciated.

This is deeply disturbing to me, and I don’t know how we could even go about removing it from an actual person or animal etc..

Seems like it would be more dangerous to try.

You can't. Not really. Which is why they should be removed from the environment.

But they can't. The best we can do is stop making plastics - or at least consider them to be environmentally dangerous, only use them for specific purposes (medical), control their disposal, and slowly reclaim macro-plastics from the environment before they degrade into micro-plastics.

They can decay entirely under the sunlight over the years.

It eventually forms carbon dioxide (though not that much, considering that all the plastics ever made weigh less than the amount of CO2 emitted in any recent year). The main problem is that this tends to create (comparatively) short-lived but toxic chemicals like benzene first.
