New glass sponges (Porifera: Hexactinellida) from deep waters of the central Aleutian Islands, Alaska
Hexactinellida from deep-water communities of the central Aleutian Islands, Alaska, are described. They were mostly collected by the remotely operated vehicle 'Jason II' from 494–2311 m depths during a 2004 RV 'Roger Revelle' expedition, but one shallow-water species collected wi...
