What is the function of the epicoracoid cartilage?

The epicoracoid cartilage, found in some vertebrates like certain fish and amphibians, serves primarily as a supportive structure for the shoulder girdle. It provides attachment points for muscles and helps stabilize the pectoral fin or limb. Additionally, it contributes to the overall strength and flexibility of the skeletal framework in the region. In some species, it may also play a role in facilitating movement and locomotion.
