translate "spikes" on a monster or dragon?

Question

How do you say spikes as in spikes on a monster or dragon?

Answer 1

Pincho seems to be ok

Dragones

Tiene ojos amarillos, cuernos broncíneos y pincho de un color similar que surgen de su larga cola.

and

en lugar de una cola con pinchos - instead of a spiked tail ...

also

ya que tienen los pinchos bien desarrollados al nacer. - they have well developed spikes at birth

Answer 2

That's a good one. Rather than a single word I'd probably go for a descriptive expression, "protuberancias puntiagudas", eg: "una fila de protuberancias puntiagudas recorría el cuerpo del dragón". You could also say "pincho", but only if they were really thin, as the thorns on a rose or the spines in a fish.
