*All species have ''Frontal'' and ''Maxillary'' systems
*All species have ''Frontal'' and ''Maxillary'' systems
**''Frontal'': consists of space(s) within the bones between the cranial cavity and the [[Nasal cavity - Anatomy & Physiology|nasal cavity]].
**''Frontal'': consists of space(s) within the bones between the cranial cavity and the [[Nasal cavity - Anatomy & Physiology|nasal cavity]].
**''Maxillary'': this is the largest sinus, and consists of the space within the caudolateral part of the upper jaw, above the caudal cheek [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|teeth]]. This increases with age due to wearing and ventral relocation of the [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|teeth]].
