Yeah, but I doubt sailors have four skulls. The manual just says that they're souls. Here's a scan, for reference.
As for defense, there is, of course, Gorea. Granted that most of it is lore, there's this:

Gorea attacks six guys who aren't Samus:

Please excuse the quality, it's the best I could find. That same attack does very little to Samus. At one point point Samus' ship has to intercept a telepathic message for Samus, as she apparently can't recieve them.
Now, magic is harder, but I suppose Mogenar will have to do.

Specifically, his rune covered magic hands, though there are a few other such attacks.

Reptilicus also blast Samus with magic, though it's less common.
