Myomeres shark
WebA broad muscle located behind the spiracle. The cranial part of this muscle is sometimes considered the epihyoid/ hyoidmandibular levator. Third to sixth dorsal constrictors. … WebUnlike the cyclostomes, where the myomeres form a series of essentially vertical strips of muscle, the myomeres of all jawed fishes are folded in a complex fashion. This development is related to the development of a more powerful swimming ability in the jawed fishes.
