axostyle

Description:

Saccinobaculus (sax-in-o-back-you-lus) (snake-in-a-sack) is a highly active oxymonad flagellate in which the massive contractile axostyle inside the cell seems to have a life of its own. Axostyle curves around the nucleus before extending the length of the cell. Four flagella emerging from anterior right corner. Endobiotic in the gut of the wood-eating cockroach, Cryptocercus. Differential interference contrast.
