Microtubule doublet

Paired microtubule unit composed of two attached hollow tubules, one a complete circular microtubule and the other a partial incomplete tubule sharing part of its wall, forming an asymmetrical doublet. In cross section it appears as two closely fused circular-to-crescent profiles with distinct hollow centers, sometimes giving a peanut-like or figure-eight outline. It may also be shown in side view as two parallel hollow tubes joined along one side.
