How does one extrude something like the spines of a blowfish?

For simplicity, I'll use a circle. Is it possible to extrude a lot of circles in different directions--similar to the spines on a blowfish? (http://cdn.zmescience.com/wp-content/uploads/2014/12/blowfish.jpg).

Or do I have to make a lot of drawings and align them individually in different directions?
