Thanks, WikiMedia!

One of the oldest clades of multicellular animals, though exactly when it split off from other animals during the Cambrian Explosion is still TBD. Like yesterday, another silent initial C-, also inherited from an Ancient Greek root where it was pronounced -- in this case kten-, comb + -phóros, bearing.
