Remains variably cartilaginous even in adults of most teleosts, but there are also dermal elements fused to some of these bones. Two main sets of cartilage bones form the ethmoid region, which is the paired lateral ethmoids (or parethmoids) and the median chondral ethmoid (or supraethmoid). There are two sets of dermal bones in this region which is or the median often dentigerous (tooth bearing ) vomer, which may be absent in a few teleosts, , and the nasals which are lateral to ethmoid region.
