The only species of boring sponge
found in the study area is Cliona celata; however, the holes created by boring sponges
can easily be distinguished from those created by the molluscan predators examined in our study.
Secondary infections and stressors, including the effect of senescence, boring worm (Polydora sp.), and boring sponge (Cliona vastifica), were examined.
Scallops with gray and brown muscles have been reported from Nova Scotia to Narragansett Bay and were associated with intracellular prokaryotes (rickettsia-like bacterium) in the gills, extensive invasion of the shell by boring sponge (Cliona vastifica) and polychaete worms (Polydora sp.), and age, that is, large, old scallops (Stevenson 1936, Medcof 1949, Gulka et al.
You either lick off all the icing first, then munch unhappily on the boring sponge
, or open your mouth wider than the Channel Tunnel in a hopeless bid to fit it all in at once.
Substrate destruction and sediment production by the boring sponge Cliona caribbaea on Grand Cayman Island.
Boring sponges and the modelling of coral reefs in the east Pacific Ocean.
Rocky reef with bright yellow "boring" sponges - on these chalk reefs, several characteristic species which bore into the soft rock are found, including the large yellow boring sponge
'I see the Cyclamen as a fruitcake -it's uniform quality all the way through, whichever way you cut it, unlike the majority of houses built at the moment, which are more like a sponge -iced at the front, but boring sponge
in the middle.'
Species of boring sponge
in the genus Cliona are widespread bioeroders on all types of calcareous substrates (Wells 1959, Goreau & Hartman 1963, MacGeanchy 1977), and bioerosion by sponges can be severe enough to damage the structural integrity of calcareous reefs (Rutzler 1975).
Significance of the boring sponge
Cliona for the origin of fine grained material of carbonate sediments.
ABSTRACT Several restored oyster (Crassostrea virginica Gmelin) reefs in Pamlico Sound, North Carolina, have experienced recent population crashes, potentially caused in part by clionid boring sponge
infestation of the marl rock (a calcium carbonate-mud composite material) commonly used as a reef substrate and of the shells of oysters that colonize the marl reef foundation.
ABSTRACT The boring sponge
Cliona celata poses an ongoing threat to the quality of eastern oysters Crassostrea virginica cultured in Baie St-Simon, Shippagan, New Brunswick, Canada.
