Shark interbranchial septum function
WebbThe interbranchial septa extend well beyond the branchial lamellae, then each bends posteriorly to form a flap which protect the lamellae as well as external gill-slit. The inner part of each interbranchial septum has a supporting cartilaginous visceral arch with slender gill-rays. http://www.pc.maricopa.edu/Biology/ppepe/BIO145/lab04_3.html
