The fiber strain (εf) experienced by the longitudinal red muscle fibers is equivalent to the longitudinal strain (εx). The deeper white muscle fibers fishes show diversity in arrangement. This behavior is also most commonly found among sharks, such as the grey nurse shark, but has also been reported for Nomorhamphus ebrardtii. In many species of fish, fins have been modified to allow Internal fertilisation. White muscles are used for bursts of activity, such as jumping or sudden bursts of speed for catching prey. Mostly fish have white muscles, but the muscles of some fishes, such as scombroids and salmonids, range from pink to dark red.

Some viviparous fish exhibit oophagy, in which the developing embryos eat other eggs produced by the mother. Valves inside the mouth keep the water from escaping. The gill arches of bony fish typically have no septum, so that the gills alone project from the arch, supported by individual gill rays. Labyrinth fish (such as gouramis and bettas) have a labyrinth organ above the gills that performs this function. A few other fish have structures resembling labyrinth organs in form and function, most notably snakeheads, pikeheads, and the Clariidae catfish family. These type of eggs can also be very small and fragile. The gills’ large surface area tends to create a problem for fish that seek to regulate the osmolarity of their internal fluids.
