Ultrastructure of the collagen fibrils in the coelacanth

The collagen fibrils in the rectal gland capsule of the coelacanth Latimeria chalumnae arec. 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 molecu...

Description
Summary:The collagen fibrils in the rectal gland capsule of the coelacanth Latimeria chalumnae arec. 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 inLatimeria are shorter, a feature they presumably share with lower tetrapods.
