(7) The central axis includes the paraglossal, basihyal, and urohyal bones and articulates with the hyoid horns, comprising the ceratobranchial
and epibranchial bones (Fig 4c).
, cleithrum and gill arches were the initial skeletal structures appeared at 3 DPH that supported the vital life functions such as feeding and respiration.
Proximally, this cartilage is fused with the first ceratobranchial
cartilage and articulated with the distal margin of the first hypobranchial cartilage.
The inner row lies towards the 5th ceratobranchial
, the outer row towards the 1st gill arch.
Gill-rakers moderate in size; first branchial arch: 6 rakers in epibranchial and 10-11 in ceratobranchial
Five new species of genus Astyanax Baird & Girard, 1854 from Rio Iguacu, Parana, Brazil (Ostariophysi, Characiformes, Characidae)/ Cinco novas especies do genero Astyanax Baird & Girard, 1854 do Rio Iguacu, Parana, Brasil (Ostariophysi, Characiformes, Characidae)
 Distal edge of first hypobranchial (Costa 2004a) (CI: 1.00; RI: 1.00): (0) articular face restricted to cartilaginous head of first ceratobranchial
; (1) articular face anteriorly expanded.
Each gill arch is divided into a long ceratobranchial
part and short epibranchial part.
The hyoid apparatus of the Chinese goose is composed of a single entoglossal bone, paired rostral basibranchial bones, an urohyal bone, paired ceratobranchial
bones, and paired epibranchial bones.
Fully formed gill rakers, only present on leading edge of first ceratobranchial
, are 8 (from one cleared and stained L.
