Comments: T. indivisa provides a habitat for 12 bacteria and species groups. It contains bacterial aggregates in their tentacles epidermis which contains hundreds of tightly packed, differently shaped endobacteria. T. indivisa is also a habitat for the potentially pathogenic Endozoicimonas elysicola. |
