The Kakuja resembling a centipede is likely nothing more than a psychological thing, since Rinkaku being able to shape their kagune is well-established. Not only was the animal itself a significant moment in his torture, but Kaneki embraces the motif for himself so it isn't a surprise when his Kakuja takes on some of those traits. It's Mimicry, not any sort of absorption of traits.

As for the centipede, I think the fact it's been embedded in someone's ear for hours/days simply means that it's covered in gore.
