How many chromisines in lamellae?

Chromisines, a subfamily of the family Pomacentridae, typically have several lamellae in their gill structures, which can vary among species. Lamellae are thin, plate-like structures that increase the surface area for gas exchange in fish. The exact number of lamellae can differ based on the species and their specific adaptations to their environments. Generally, chromisines may exhibit a range of 10 to 30 lamellae per gill arch, depending on the species.
