The collagen fibrils in the rectal gland capsule of the coelacanth Latimeria chalumnae are c . 127 nm in diameter and resemble those fibrils that play an active mechanical role in trout skin. The fibrils having periodicity of about 54 nm and seven intrabands per period suggest that the collagen molecules in Latimeria are shorter, a feature they presumably share with lower tetrapods.
