FRESHWATER SPONGES (PORIFERA: SPONGILLIDAE) IN THE FAROEISLANDS
in both species are quite tolerant to envi-
ronmental changes (Fell and Bazer, 1990;
Fell and Levasseur, 1991). They were in all
probability carried along by birds.
Acknowledgements
I heartily thank Frank Jensen, Natural History Museum,
Aarhus, and Hans Tore Rapp, Department of Fisheries
and Marine Biology, Bergen, for allowing me to use
their samples from Faroese localities. A special thank
goes to Ole Bennike, Geological Survey of Denmark
and Greenland, Copenhagen, for placing at my disposal
gemmules and information from a core taken in
Skálafjørður and for comments on the manuscript.
