No, I haven't noticed spikes on their backs, much less from that picture.

@Maki: Want to make them look scary? Give them one big, round eye in the center. But one that is not "only red", but more like "huge human eye with red pupil". And probably do like some other animals do; I've heard there was a snake or reptile that shot blinding venom from it's eyes when threatened.
