- Аннотация: The ascidian Styela clava is an invasive species that easily colonizes new water areas and has a widedistribution. A previously undescribed typhlosole was discovered in S. clava and studied using histologicaltechniques, transmission electron microscopy and computer microtomography. The typhlosole is a large foldof the dorsal intestinal wall that starts in the lower quarter of the stomach and continues to the rectum. Itsshape varies greatly: from a rounded protrusion to a spirally twisted fold. The typhlosole is formed by theintestinal epithelium and a thick connective tissue layer, in which pyloric tubules and blood vessels areextended. The epithelium consists of glandular, ciliated, and nonciliated cells demonstrating apocrine secretion.The typhlosole intensifies the food digestion and absorption of nutrients. The features observed in thetyphlosole may contribute to a high digestion efficiency even in low-productive waters, determining the biologicalsuccess of this species.
