Are there any unique pet traits and/or abilities that certain pets have?

like for example i found out that when you summon arikara(wind serpent) it gets summoned in a poof a smoke. i also heard that bangalash(and maybe other unique pets) might have extra unique abilities or passives. are there any other traits like these?

King Bangalash has a "hidden skill" of Cobra Reflexes.  If you ever untrain his talents, this "hidden skill" of his will be lost and cannot be recovered (short of Abandoning him and re-Taming him).

are you sure that king banglash has that on elysium? i heard it depends on the server or that it might even be a TBC thing.

Yo, sorry for the late reply.

There are a few cool rares with special attack speeds. I could list them off, but here, I have a pet tutorial:
