A trophosome is a highly vascularised organ found in some animals that houses symbiotic bacteria that provide food for their host. Trophosomes are located in the coelomic cavity in the vestimentiferan tube worms (Siboglinidae, e.g. the giant tube worm Riftia pachyptila) and in symbiotic flatworms of the genus Paracatenula.

  • Un trophosome est un organe que l'on retrouve chez certains animaux, il abrite des bactéries symbiotiques prodiguant de la nourriture à leur hôte. On le trouve par exemple chez des vers tubicoles extrêmophiles, tels que le Riftia pachyptila, qui ne possède pas de système digestif. (fr)

  • Il trofosoma è un tessuto specializzato presente nelle specie di policheti (pogonofori). Uno dei suoi vantaggi è di permettere a questi organismi di sopravvivere negli abissi oceanici in prossimità di black smoker e dov'è presente un'elevata concentrazione di solfuri. (it)
  • 營養體(Trophosome;源自trophē),亦作滋養體,是一種在部分原口動物(例如:鬚腕科物種)內的深綠棕色器官,用來儲存,以為其宿主提供完全營養。巨型管蟲及共生性扁形动物门的屬物種均有這種器官。在這些動物體內,營養體的內共生細菌會將蟲體的硫或硫化物氧化,透過固碳作用產生有機分子,使之為宿主所使用,為其提供營養及能量。這個過程叫做化能合成或岩石自养生物。 (zh)
  • Een trofosoom is een orgaan, als een soort middendarm, met symbiotische bacteriën dat bij sommige dieren voorkomt en zorgt voor het voedsel van hun gastheer. Trofosomen bevinden zich in de coelome lichaamsholte van: * buiswormen (Siboglinidae) behorend tot de voormalige stam , bijvoorbeeld bij de reusachtige kokerworm (Riftia pachyptila]), * symbiotische platwormen van het geslacht . * rondwormen, zoals bij de rondwormen van de familie Mermithidae (nl)
