Ancistrum is a marine ciliate that inhabits the mantle cavity of mytiliid mussels. This image shows a good view of the macronucleus, mitochondria with tubular cristae, and what are probably flask-shap...

Ancistrum is a marine ciliate that inhabits the mantle cavity of mytiliid mussels. This image shows a good view of mitochondria with tubular cristae and what are probably flask-shaped endosomes. This ...

Here a mitochondrion is sliced approximately through its midplane, so both its outer membrane and the infoldings of its inner membrane are clearly seen. The organization of the inner membrane is parti...
