Thaumatocrinus jungerseni assemblage on Atlantic abyssal mud
Description (English)
Hughes and Gage (2004) describe this biotope from the mouth of Rockall Trough at 3580m dominated by the comatulid crinoid Thaumatocrinus jungerseni on fine silt or pelagic ooze. It is possible that this site experiences increased current speeds as a result of the constriction of the topography in this area, making it favourable to suspension feeding organisms such as crinoids. This assemblage may therefore be a variation on the Psychropotes longicauda and Oneirophanta mutabilis assemblage. This assemblage was described based on literature only.
