Maybe what they’re trying to describe is a torus

Are there non-circular cylinders or what does that even mean.

No they’d only model a bull as a torus.

Now, how exactly is a penguin toroidal?
letsgo@lemm.ee 7 months ago
It has a single hole through its body from its mouth to its arsehole. IANAB but I think all other holes have at least a membrane between one end and the other. So it’s topologically equivalent to a teacup and a torus.

Imagine a donut-shaped penguin, love it! 😸

Maybe having halfspheres at the top and bottom? So more like a gas tank, less like a piece of sausage.

only thing i can figure is maybe technically you could call an ellipsoidal prism a cylinder also? seems like a stretch.

Yeah, I also thought that there might be a cylinder based on a ellipse. Not very common but possible

Maybe they meant prism, since a cylinder is technically one.
