The Google dictionary says it's a zoological term "approximately conical in shape".
The Wikipedia panel says "In geometry a conoid is a ruled surface, whose rulings fulfill the additional conditions: All rulings are parallel to a plane, the directrix plane. All rulings intersect a fixed line, the axis." The graphics are... nothing intuitive.
The M-W link in the search results says "a cone-shaped structure; especially : a hollow organelle shaped like a truncated cone that occurs at the anterior end of the organism".
None of this seeming relevant, I clicked on the Image tab and it's all these complicated Mathematica-style graphs of things that are very much not cones.
I see other people in the HN comments similarly have no idea.
Can you please explain what you saw on screen? What did the captcha think was a conoid...? Like, traffic cones or something?

the cone on the bottom spins when you have the right of way.
