It's a cell, but the (informal) idea is that a big living thing is made of a lot of small cells. If there is a catastrofic extintion and only these things survive, would and alien biologist clasify them as a huge cell or as a blob?
> How is it clear that it evolved from animals? It seems like clear protist to me.
My bad. You are right. I probaly mean from a normal living thing with small cells with only one nuclei.
> Skeletal muscle fibers are made when myoblasts fuse together; muscle fibers therefore are cells with multiple nuclei, known as myonuclei, with each cell nucleus originating from a single myoblast. The fusion of myoblasts is specific to skeletal muscle, and not cardiac muscle or smooth muscle.

Side note: I'm not sure it's related, but as a curiosity, our muscles have cells with multiple nuclei https://en.wikipedia.org/wiki/Muscle_cell
