Byssus

 

(1) An excretion of the byssal gland, found in the so-called feet of many bivalve mollusks. Immediately upon expulsion, byssus hardens and forms durable silky filaments by which mollusks fasten themselves to underwater objects. In antiquity a special cloth, vysson, was prepared from the byssus excreted by the large mollusk pinna.

(2) A roe disease of freshwater fish caused by certain fungi of the genera Saprolegnia and Achy la.

This can be achieved acoustically over the region SWB, by backscatter contrast mapping for mussel reefs, which form as a result of the interaction between tidally moved sand and the long-term anchoring effect of horse mussel byssus, but not for mussel populations in other geological provinces where backscatter contrasts are notably absent.
What's more, it was a chemical match with the mussels' own byssus, the researchers report in the Jan.
Abstract: The quantities of biomass produced in gametes, somatic tissue growth, byssus formation and organic matrix in the shell were studied from September 1988 through September 1989 in an exploited population of Perna perna (L.
The ventral surface of a solitary mussel, including the byssal notch through which byssus threads attach to the ground, is in general relatively small in comparison to the total surface area of the mussel, and the posterior end of a mussel in a bed even smaller.
Two more transformations: son up on the parapet of the Martello Tower, the snot green sea reminding him of the bowl of green bile torn from his mother's rotting liver; man and sea maid from Finn's, the Barnacle with the auburn byssus, swimming into mutual ken on Thor's day, Bloomsday, June 16th, 1904.
This reallocation ensures a greater output when reproduction does commence, and the additional byssus and shell mass may allow the elevated survivorship this "strategy" requires.
Both species have common characteristics such as short life cycle, rapid growth, planktonic larval stage and the presence of byssus that explain their success in colonizing new habitats (Morton, 1973, Ricciardi, 1998).
