Proximally, this cartilage is fused with the first ceratobranchial
cartilage and articulated with the distal margin of the first hypobranchial cartilage.
The hypobranchial and the ceratobranchial
form the lower limb of a branchial arch and the epibranchial forms the upper limb (Sakamoto 1984).
2) constitutes the lower pharyngeal jaw (5th ceratobranchial
elements) of an adult judging by its size, and it is above the average of the species.
Meanwhile, the ceratobranchial
elements (CB 1-5) are rod-like in shape (Figure 4).
First gill arch with 20 rakers, three on hypobranchial, ten on ceratobranchial
and seven on epibranchial.
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.
Gill-rakers moderate in size; first branchial arch: 6 rakers in epibranchial and 10-11 in ceratobranchial

(Costa 2005b) (CI: 0.
Rakers on trailing edge of ceratobranchial
1 and on leading and trailing edges of cerato-branchials 2-3 and leading edge of ceratobranchial
4 irregularly and wealdy developed.
Anterior three gill arches each of hypobranchial, ceratobranchial
, epibranchial and pharyngobranchial, fourth arch of ceratobranchial
and epibranchial, fifth arch comprising single ceratobranchial
The order of the ceratobranchials
is distinguished by their associations with the hypobranchials, their position relative to the pectoral girdle cartilage (which develops normally), and the presence of pharyngeal teeth on the fifth ceratobranchial
